      <para>An <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control works with a class that you create. You create methods that retrieve and update data, and you provide the names of those methods to the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control in markup. During rendering or postback processing, the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> calls the methods that you have specified.</para>
      <para>There is no visual rendering of the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control. As a result, the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> does not support visual features such as the <see cref="P:System.Web.UI.DataSourceControl.EnableTheming" /> or <see cref="P:System.Web.UI.DataSourceControl.SkinID" /> property.</para>

        <h2>Purpose</h2>
      </format>
      <para>A very common application design practice is to separate the presentation layer from business logic and to encapsulate the business logic in business objects. These business objects form a distinct layer between the presentation layer and the data tier, resulting in a three-tier application architecture. The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control enables developers to use an ASP.NET data source control while retaining their three-tier application architecture.</para>
      <para>The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control uses reflection to create instances of business objects and to call methods on them to retrieve, update, insert, and delete data. The <see cref="P:System.Web.UI.WebControls.ObjectDataSource.TypeName" /> property identifies the name of the class that the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> works with. The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control creates and destroys an instance of the class for each method call; it does not hold the object in memory for the lifetime of the Web request. This is a serious consideration if the business object that you use requires many resources or is otherwise expensive to create and destroy. Using an expensive object might not be an optimal design choice, but you can control the life cycle of the object by using the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectCreating" />, <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectCreated" />, and <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectDisposing" /> events.</para>

If the methods are static (Shared in Visual Basic), an instance of the business object is not created, and the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectCreating" />, <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectCreated" />, and <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectDisposing" /> events are not raised.</para>

        <h2>Retrieving Data</h2>
      </format>
      <para>To retrieve data from a business object, set the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property to the name of the method that retrieves data. If the method does not return an <see cref="T:System.Collections.IEnumerable" /> or <see cref="T:System.Data.DataSet" /> object, the object is wrapped by the runtime in an <see cref="T:System.Collections.IEnumerable" /> collection. If the method signature has parameters, you can add <see cref="T:System.Web.UI.WebControls.Parameter" /> objects to the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectParameters" /> collection, and then bind them to the values that you want to pass to the method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property. In order for the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control to use the parameters, the parameters must match the names and types of the parameters in the method signature. For more information, see <format type="text/html"><a href="45fb67ee-9be7-49b7-9421-e242203dafa4">Using Parameters with the ObjectDataSource Control</a></format>.</para>
      <para>The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control retrieves data whenever the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Select" /> method is called. This method provides programmatic access to the method that is specified by <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property. The method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property is called automatically by controls that are bound to the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> when their DataBind method is called. If you set the DataSourceID property of a data-bound control, the control automatically binds to data from the data source, as needed. Setting the DataSourceID property is the recommended method for binding an <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control to a data-bound control. Alternatively, you can set the DataSource property, but then you must explicitly call the DataBind method of the data-bound control. You can call the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Select" /> method programmatically at any time to retrieve data.</para>
      <para>For more information about binding data-bound controls to data source controls, see <format type="text/html"><a href="e41adfff-8fb8-449e-9cd1-9bd49788c5f7">Binding to Data Using a Data Source Control</a></format>.</para>

        <h2>Performing Data Operations</h2>
      </format>
      <para>Depending on the capabilities of the business object that the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control works with, you can perform data operations, such as updates, insertions, and deletions. To perform these data operations, set the appropriate method name and any associated parameters for the operation that you want to perform. For example, for an update operation, set the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" /> property to the name of the business object method that performs updates and add any required parameters to the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateParameters" /> collection. If the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control is associated with a data-bound control, the parameters are added by the data-bound control. In this case, you need to ensure that the parameter names of the method match the field names in the data-bound control. The update is performed when the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Update" /> method is called, either explicitly by your code or automatically by a data-bound control. The same general pattern is followed for <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Delete" /> and <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Insert" /> operations. Business objects are assumed to perform these types of data operations one record at a time, rather than batched.</para>

        <h2>Filtering Data</h2>
      </format>
      <para>The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control can filter data that is retrieved by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property, if the data is returned as a <see cref="T:System.Data.DataSet" /> or <see cref="T:System.Data.DataTable" /> object. You can set the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.FilterExpression" /> property to a filtering expression by using a format string syntax and bind values in the expression to parameters that are specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.FilterParameters" /> collection.</para>

        <h2>Caching</h2>
      </format>
      <para>Although the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> does not retain the instance of the business object across multiple requests, it can cache the result of calling the method identified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property. While the data is cached, subsequent calls to the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Select" /> method return the cached data instead of creating the business object and calling its <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> using reflection. Caching lets you avoid creating the object and calling its data method at the expense of memory on the Web server. The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> automatically caches data when the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.EnableCaching" /> property is set to true, and the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.CacheDuration" /> property is set to the number of seconds that the cache stores data before the cache is discarded. You can also specify a <see cref="P:System.Web.UI.WebControls.ObjectDataSource.CacheExpirationPolicy" /> property and an optional <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SqlCacheDependency" /> property. The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control allows you to cache all types of data, but you should not cache objects that retain resources or state that cannot be shared to service multiple requests (for example, an open <see cref="T:System.Data.SqlClient.SqlDataReader" /> object), because the same instance of the object will be used to service multiple requests.</para>

          <description>
            <para>Data source paging is supported, if the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> method contains parameters for the maximum number of records to retrieve and the index of the first record to retrieve. The names of those parameters must be set in the  <see cref="P:System.Web.UI.WebControls.ObjectDataSource.MaximumRowsParameterName" /> and <see cref="P:System.Web.UI.WebControls.ObjectDataSource.StartRowIndexParameterName" /> properties, respectively. A data-bound control might be able to perform paging itself, even if the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control does not support paging directly in the method specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property. The requirement for the data-bound control to be able to do this is that the method specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property return an object that implements the <see cref="T:System.Collections.ICollection" /> interface.</para>

      </format>
      <para>You can use the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control with a LINQ to SQL class. To do so, you set the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.TypeName" /> property to the name of the data-context class. You also set the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" />, <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" />, <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertMethod" />, and <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DeleteMethod" /> methods to the methods in the data-context class that perform the corresponding operations. You must create an event handler for the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectDisposing" /> event in order to cancel disposing of the data-context class. This step is necessary because LINQ to SQL supports deferred execution, whereas the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control tries to dispose the data context after the Select operation.

For an example of how to cancel the disposing of a data context class, see the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectDisposing" /> event.</para>

          <para>This property determines whether parameters for old and new values are applied to the method specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" /> property. For example, if the method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property returns a <see cref="T:System.Data.DataTable" /> control with the columns Name and Number, and the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.ConflictDetection" /> property is set to the <see cref="F:System.Web.UI.ConflictOptions.OverwriteChanges" /> field, parameters are created for Name and Number for the Update method. If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.ConflictDetection" /> property is set to the <see cref="F:System.Web.UI.ConflictOptions.CompareAllValues" /> value, parameters are created for Name, Number, original_Name, and original_Number. (The exact name of the parameters for the original values depends on the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.OldValuesParameterFormatString" /> property.) The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> then determines whether the method that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" /> property has parameters that match. </para>
          <para>Concurrency control is a technique that data stores use to control how data is read and changed in the store when multiple clients are accessing and manipulating the same data. For example, one client reads data and presents it to a user, while another client reads the same data and presents it to a different user. If both users update the data and submit it to the data storage, an unexpected result might occur, because both clients might provide different values for the same data. This is considered a conflict. By setting the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.ConflictDetection" /> property to the <see cref="F:System.Web.UI.ConflictOptions.CompareAllValues" /> value, the Update method can then compare the old and new values to the original data source to detect conflicts and handle them as necessary.</para>
          <para>The <see cref="P:System.Web.UI.WebControls.ObjectDataSource.ConflictDetection" /> property delegates to the <see cref="P:System.Web.UI.WebControls.ObjectDataSourceView.ConflictDetection" /> property of the <see cref="T:System.Web.UI.WebControls.ObjectDataSourceView" /> object that is associated with the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control.</para>

The <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property allows you to specify a type that has a property for each data field. Then, instead of passing several parameters to the method, the runtime creates one object and sets all of its properties. This one object is added to the parameters collection for the method call.</para>
          <para>The type that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property must have a default constructor that has no parameters, so the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control can create an instance of the type. The type must also have settable properties that allow the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control to populate the object with values that are passed from the data-bound control. The property names on the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control are expected to exactly match the parameter names of values that are passed by the data-bound control.</para>
          <para>When the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property is set and the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control is associated with a data-bound control, the methods that are specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertMethod" /> and <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DeleteMethod" /> properties must each have one parameter of the type that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property. If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.ConflictDetection" /> property is set to the <see cref="F:System.Web.UI.ConflictOptions.OverwriteChanges" /> value, the method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" /> property must have one parameter of the type that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property. If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.ConflictDetection" /> property is set to the <see cref="F:System.Web.UI.ConflictOptions.CompareAllValues" /> value, the method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" /> property must have two parameters of the type that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property. The first parameter contains the original values; the second parameter contains the new values.</para>

              <para>From the data-bound control, at run time.</para>

              <para>From the Deleting method, declaratively.</para>
            </item>
          </list>
          <para>First, any parameters that are generated from data-bound controls are added to the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DeleteParameters" /> collection. For example, if the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control is bound to a <see cref="T:System.Web.UI.WebControls.GridView" /> control that has the columns Name and Number, parameters for Name and Number are added to the collection. The exact name of the parameter depends on the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.OldValuesParameterFormatString" /> property. The data type of these parameters is string. Next, the parameters that are listed in the DeleteParameters element are added. If a parameter in the DeleteParameters element is found with the same name as a parameter that is already in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DeleteParameters" /> collection, the existing parameter is modified to match the parameter that is specified in the DeleteParameters element. Typically, this is used to modify the type of the data in the parameter. Finally, you can programmatically add and remove parameters in the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.Deleting" /> event, which occurs before the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Delete" /> method is run. The method is resolved after the parameters are merged. Method resolution is discussed in the next section.</para>

          </format>
          <para>When the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Delete" /> method is called, the data fields from the data-bound control, the parameters that were created declaratively in the DeleteParameters element, and the parameters that were added in the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.Deleting" /> event handler are all merged. (For more information, see the preceding section.) The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> object then attempts to find a method to call. First, it looks for one or more methods with the name that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DeleteMethod" /> property. If no match is found, an <see cref="T:System.InvalidOperationException" /> exception is thrown. If a match is found, it then looks for matching parameter names. For example, suppose the type that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.TypeName" /> property has two methods named DeleteARecord. One DeleteARecord has one parameter, <paramref name="ID" />, and the other DeleteARecord has two parameters, <paramref name="Name" /> and <paramref name="Number" />. If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DeleteParameters" /> collection has only one parameter named <paramref name="ID" />, the DeleteARecord method with just the <paramref name="ID" /> parameter is called. The type of the parameter is not checked in resolving the methods. The order of the parameters does not matter. </para>
          <para>If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property is set, the method is resolved in a different way. The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> looks for a method with the name that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DeleteMethod" /> property that takes one parameter of the type that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property. In this case, the name of the parameter does not matter.</para>

          <para>Paging by the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control is handled by setting the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.EnablePaging" />, <see cref="P:System.Web.UI.WebControls.ObjectDataSource.StartRowIndexParameterName" />, <see cref="P:System.Web.UI.WebControls.ObjectDataSource.MaximumRowsParameterName" />, and <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectCountMethod" /> properties of the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> and defining a select method in the business object with the proper parameters. When the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.EnablePaging" /> property is set to true, the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectParameters" /> collection includes two additional parameters for the first row that is requested and the number of rows that are requested. These two parameters are named as defined by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.StartRowIndexParameterName" /> and <see cref="P:System.Web.UI.WebControls.ObjectDataSource.MaximumRowsParameterName" /> properties. The Select method should return the requested number of rows, starting at the specified index. Because the data might not divide evenly by the page size, the last page might contain fewer rows. Thus, the number of rows that are requested is actually the maximum number of rows that are returned. </para>
          <para>When paging is enabled on the associated data-bound control, the data-bound control calls the Select method with the start index and number of rows that are required. Additionally, if the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectCountMethod" /> property is set, the data-bound control calls the method before rendering the pager controls. For example, if a <see cref="T:System.Web.UI.WebControls.GridView" /> control has paging enabled with a page size of 5, and the method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectCountMethod" /> property returns 20, only 4 pages are displayed in the pager.</para>
          <para>The <see cref="P:System.Web.UI.WebControls.ObjectDataSource.EnablePaging" /> property delegates to the <see cref="P:System.Web.UI.WebControls.ObjectDataSourceView.EnablePaging" /> property of the <see cref="T:System.Web.UI.WebControls.ObjectDataSourceView" /> object.</para>

          <para>The method that is identified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertMethod" /> property can be an instance method or a static (Shared in Visual Basic) method. If it is an instance method, the business object is created and destroyed each time the method specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertMethod" /> property is called. You can handle the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectCreated" /> and <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectCreating" /> events to work with the business object before the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertMethod" /> property is called. You can also handle the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectDisposing" /> event that is raised after the method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DeleteMethod" /> property is called. If the business object implements the <see cref="T:System.IDisposable" /> interface, the <see cref="M:System.IDisposable.Dispose" /> method is called before the object is destroyed. If the method is static (Shared in Visual Basic), the business object is never created and you cannot handle the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectCreated" />, <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectCreating" />, and <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectDisposing" /> events.</para>

          <para>Parameters are added to the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertParameters" /> collection from three sources:</para>
          <list type="bullet">
            <item>
              <para>From the data-bound control, at run time.</para>
            </item>
            <item>
              <para>From the InsertParameters element, declaratively.</para>
            </item>
            <item>
              <para>From the Inserting method, programmatically.</para>
            </item>
          </list>
          <para>First, any parameters that are generated from data-bound controls are added to the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertParameters" /> collection. For example, if the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control is bound to a <see cref="T:System.Web.UI.WebControls.GridView" /> control that has the columns Name and Number, the parameters for Name and Number are added to the collection. The data type of these parameters is string. Next, the parameters that are listed in the InsertParameters element are added. If a parameter in the InsertParameters element is found with the same name as a parameter that is already in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertParameters" /> collection, the existing parameter is modified to match the parameter that is specified in the InsertParameters element. Typically, this is used to modify the type of the data in the parameter. Finally, you can programmatically add and remove parameters in the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.Inserting" /> event, which occurs before the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Insert" /> method is run. The method is resolved after the parameters are merged. Method resolution is discussed in the next section.</para>
          <block subset="none" type="note">
            <para>You should validate any parameter value that you receive from the client. The runtime simply substitutes the parameter value into the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertMethod" /> property.</para>

          <format type="text/html">
            <h2>Method Resolution</h2>
          </format>
          <para>When the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Insert" /> method is called, the data fields from the data-bound control, the parameters that were created declaratively in the InsertParameters element, and the parameters that were added in the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.Inserting" /> event handler are all merged. (For more information, see the preceding section.) The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> object then attempts to find a method to call. First, it looks for one or more methods with the name that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertMethod" /> property. If no match is found, an <see cref="T:System.InvalidOperationException" /> exception is thrown. If a match is found, it then looks for matching parameter names. For example, suppose a type that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.TypeName" /> property has two methods named InsertARecord. One InsertARecord has one parameter, <paramref name="ID" />, and the other InsertARecord has two parameters, <paramref name="Name" /> and <paramref name="Number" />. If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertParameters" /> collection has only one parameter named <paramref name="ID" />, the InsertARecord method with just the <paramref name="ID" /> parameter is called. The type of the parameter is not checked in resolving the methods. The order of the parameters does not matter. </para>
          <para>If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property is set, the method is resolved in a different way. The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> looks for a method with the name that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertMethod" /> property that takes one parameter of the type that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property. In this case, the name of the parameter does not matter.</para>

          <para>The names and types of the parameters that are contained in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertParameters" /> collection must match the names and types of the parameters that are in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertMethod" /> property signature. The parameter names are case sensitive. When working with data-bound controls that supply parameters, such as the <see cref="T:System.Web.UI.WebControls.GridView" /> and <see cref="T:System.Web.UI.WebControls.DetailsView" /> controls, the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control automatically merges any parameters that are explicitly specified in the collection with the parameters that are provided by the data-bound control. This is important because data-bound controls always supply their parameters as <see cref="T:System.String" /> types, and if the method signature includes numeric or date types, you must explicitly include a parameter in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.InsertParameters" /> collection with the correct type. Otherwise, the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control attempts to cast the parameters according to the type that is defined by the parameters in the collection.

          <para>The method that is identified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property can be an instance method or a static (Shared in Visual Basic) method. If it is an instance method, the business object is created and destroyed each time the method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property is called, except that the same instance is used to call the method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property and the method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectCountMethod" /> property. The <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Select" /> method returns an <see cref="T:System.Collections.IEnumerable" /> interface. However, to enable caching and filtering scenarios, the return value must be a <see cref="T:System.Data.DataSet" /> object. While the <see cref="T:System.Data.DataSet" /> class does not implement the <see cref="T:System.Collections.IEnumerable" /> interface, the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control automatically extracts the default <see cref="T:System.Data.DataView" /> control, which implements the <see cref="T:System.Collections.IEnumerable" />.</para>
          <para>Before the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Select" /> operation is performed, the <see cref="M:System.Web.UI.WebControls.ObjectDataSourceView.OnSelecting(System.Web.UI.WebControls.ObjectDataSourceSelectingEventArgs)" /> method is called to raise the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.Selecting" /> event. You can handle the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.Selecting" /> event to examine the values of the parameters and to perform any preprocessing before a <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Select" /> operation. To perform a data retrieval operation, the <see cref="T:System.Web.UI.WebControls.ObjectDataSourceView" /> object uses reflection to create an instance of the object that is identified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.TypeName" /> property. It then calls the method that is identified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property, using any associated <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectParameters" /> properties. After the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Select" /> operation completes, the <see cref="M:System.Web.UI.WebControls.ObjectDataSourceView.OnSelected(System.Web.UI.WebControls.ObjectDataSourceStatusEventArgs)" /> method is called to raise the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.Selected" /> event. You can handle the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.Selected" /> event to examine any return values, output parameters, and exceptions, and to perform any post-processing.</para>
          <para>If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property returns a <see cref="T:System.Data.DataSet" />, <see cref="T:System.Data.DataTable" />, or <see cref="T:System.Data.DataView" /> object and caching is enabled, the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> retrieves data from and saves data to the cache during the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Select" /> operation. The cache is created, discarded, or refreshed based on the caching behavior that is specified by the combination of the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.CacheDuration" /> and <see cref="P:System.Web.UI.WebControls.ObjectDataSource.CacheExpirationPolicy" /> properties.</para>
          <para>If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectMethod" /> property returns a <see cref="T:System.Data.DataSet" /> or <see cref="T:System.Data.DataTable" /> object, and a <see cref="P:System.Web.UI.WebControls.ObjectDataSource.FilterExpression" /> property has been specified, it is evaluated with any supplied <see cref="P:System.Web.UI.WebControls.ObjectDataSource.FilterParameters" /> properties and the resulting filter is applied to the list of data during the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Select" /> operation.</para>
          <para>The <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Select" /> method delegates to the <see cref="Overload:System.Web.UI.WebControls.ObjectDataSourceView.Select" /> method of the <see cref="T:System.Web.UI.WebControls.ObjectDataSourceView" /> that is associated with the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control.</para>

(For more information, see the preceding section.) The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control then attempts to find a method to call.

If no match is found, an <see cref="T:System.InvalidOperationException" /> exception is thrown. If a match is found, it then looks for matching parameter names. For example, suppose a type that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.TypeName" /> property has two methods named SelectARecord. One SelectARecord has one parameter, <paramref name="ID" />, and the other SelectARecord has two parameters, <paramref name="Name" /> and <paramref name="Number" />. If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.SelectParameters" /> collection has only one parameter named <paramref name="ID" />, the SelectARecord method with just the <paramref name="ID" /> parameter is called. The type of the parameter is not checked in resolving the methods. The order of the parameters does not matter. </para>
          <para>If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property is set, the method is resolved in a different way.

          <para>The method that is identified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" /> property can be an instance method or a static (Shared in Visual Basic) method. If it is an instance method, the business object is created and destroyed each time the method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" /> property is called. You can handle the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectCreated" /> and <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectCreating" /> events to work with the business object before the method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" /> property is called. You can also handle the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectDisposing" /> event that is raised after the method that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" /> property is called. If the business object implements the <see cref="T:System.IDisposable" /> interface, the <see cref="M:System.IDisposable.Dispose" /> method is called before the object is destroyed. If the method is static (Shared in Visual Basic), the business object is never created and you cannot handle the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectCreated" />, <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectCreating" />, and <see cref="E:System.Web.UI.WebControls.ObjectDataSource.ObjectDisposing" /> events.</para>

          <para>Parameters are added to the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateParameters" /> collection from three sources:</para>
          <list type="bullet">
            <item>
              <para>From the data-bound control, at run time.</para>
            </item>
            <item>
              <para>From the UpdateParameters element, declaratively.</para>
            </item>
            <item>
              <para>From the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.Updating" /> event handler, programmatically.</para>
            </item>
          </list>
          <para>First, any parameters that are generated from data-bound controls are added to the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateParameters" /> collection. For example, if the <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control is bound to a <see cref="T:System.Web.UI.WebControls.GridView" /> control that has the columns Name and Number, the parameters for Name and Number are added to the collection. The exact name of the parameter depends on the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.OldValuesParameterFormatString" /> property. The data type of these parameters is string. Next, the parameters that are listed in the UpdateParameters element are added. If a parameter in the UpdateParameters element is found with the same name as a parameter that is already in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateParameters" /> collection, the existing parameter is modified to match the parameter that is specified in the UpdateParameters element. Typically, this is used to modify the type of the data in the parameter. Finally, you can programmatically add and remove parameters in the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.Updating" /> event, which occurs before the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Update" /> method is run. The method is resolved after the parameters are merged. Method resolution is discussed in the next section.</para>

            <para>You should validate any parameter value that you receive from the client. The runtime simply substitutes the parameter value into the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" /> property.</para>
          </block>
          <format type="text/html">
            <h2>Method Resolution</h2>
          </format>
          <para>When the <see cref="M:System.Web.UI.WebControls.ObjectDataSource.Update" /> method is called, the data fields from the data-bound control, the parameters that were created declaratively in the UpdateParameters element, and the parameters that were added in the <see cref="E:System.Web.UI.WebControls.ObjectDataSource.Updating" /> event handler are all merged. (For more information, see the preceding section.) The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> control then attempts to find a method to call. First, it looks for one or more methods with the name that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" /> property. If no match is found, an <see cref="T:System.InvalidOperationException" /> exception is thrown. If a match is found, it then looks for matching parameter names. For example, suppose a type that is specified by the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.TypeName" /> property has two methods named UpdateARecord. One UpdateARecord has one parameter, <paramref name="ID" />, and the other UpdateARecord has two parameters, <paramref name="Name" /> and <paramref name="Number" />. If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateParameters" /> collection has only one parameter named <paramref name="ID" />, the UpdateARecord method with just the <paramref name="ID" /> parameter is called. The type of the parameter is not checked in resolving the methods. The order of the parameters does not matter. </para>
          <para>If the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property is set, the method is resolved in a different way. The <see cref="T:System.Web.UI.WebControls.ObjectDataSource" /> looks for a method with the name that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.UpdateMethod" /> property that takes one parameter of the type that is specified in the <see cref="P:System.Web.UI.WebControls.ObjectDataSource.DataObjectTypeName" /> property. In this case, the name of the parameter does not matter.</para>
