<para>The <see cref="T:System.Web.UI.WebControls.Parameter" /> class represents a parameter in a parameterized SQL query, a filtering expression, or a business object method call that an ASP.NET data source control uses to select, filter, or modify data. <see cref="T:System.Web.UI.WebControls.Parameter" /> objects are contained in a <see cref="T:System.Web.UI.WebControls.ParameterCollection" /> object. <see cref="T:System.Web.UI.WebControls.Parameter" /> objects are evaluated at run time, to bind the values of the variables they represent to whatever method is used by a data source control to interact with data. </para>
<para>Use classes that derive from <see cref="T:System.Web.UI.WebControls.Parameter" /> with data source and data-bound controls to build Web-based data applications. These parameter classes are used by data source controls to bind specific kinds of values found in Web applications to placeholders in SQL query strings, business object method parameters, and more. The following table lists parameter types that are included in ASP.NET.</para>

<para>
<see cref="T:System.Web.UI.WebControls.Parameter" /> objects are very simple: they have a <see cref="P:System.Web.UI.WebControls.Parameter.Name" /> and a <see cref="P:System.Web.UI.WebControls.Parameter.Type" /> property, can be represented declaratively, and can track state across multiple HTTP requests. All parameters support a <see cref="P:System.Web.UI.WebControls.Parameter.DefaultValue" /> property, for cases when a parameter is bound to a value, but the value evaluates to null at run time.</para>
<para>When using a collection of <see cref="T:System.Web.UI.WebControls.Parameter" /> objects with a data source control, their order in the collection might matter. For more information on how parameters are used, see <format type="text/html"><a href="403ff44a-dd0b-484d-968e-dcd1dcd4c295">Using the SqlDataSource and AccessDataSource Controls with Parameters</a></format> and <format type="text/html"><a href="45fb67ee-9be7-49b7-9421-e242203dafa4">Using Parameters with the ObjectDataSource Control</a></format>.</para>

<see cref="T:System.Web.UI.WebControls.Parameter" /> objects are not required to have a name; however, data source controls might use the parameter name to match a <see cref="T:System.Web.UI.WebControls.Parameter" /> object in a collection with a parameter in a SQL query or business method signature. For example, the <see cref="T:System.Web.UI.WebControls.SqlDataSource" /> control can use the name of the <see cref="T:System.Web.UI.WebControls.Parameter" /> object to match a placeholder in a parameterized SQL query. Similarly, the <see cref="T:System.Web.UI.WebControls.SqlDataSource" /> control can use the name of a <see cref="T:System.Web.UI.WebControls.Parameter" /> object in the <see cref="P:System.Web.UI.WebControls.SqlDataSource.FilterParameters" /> collection to match a placeholder in the <see cref="P:System.Web.UI.WebControls.SqlDataSource.FilterExpression" /> property. In some cases, the name is not used and the order in which the <see cref="T:System.Web.UI.WebControls.Parameter" /> object is added to a <see cref="T:System.Web.UI.WebControls.ParameterCollection" /> collection is more important.

<para>A parameter's view state is the accumulation of all its property values. To preserve these values across HTTP requests, ASP.NET server controls use this property, which is an instance of the <see cref="T:System.Web.UI.StateBag" /> class, to store the property values. The values are then passed as a variable to an HTML hidden input element when subsequent requests are processed. View state is enabled for all server controls by default.</para>
