<para>ASP.NET supports a controls architecture that enables Web server controls to bind to data in a consistent fashion. Web server controls that bind to data are referred to as data-bound controls, and the classes that facilitate that binding are called data source controls. Data-bound controls that are designed to use ASP.NET data source controls derive from the <see cref="T:System.Web.UI.WebControls.BaseDataBoundControl" /> control class, which defines the base data-bound control functionality. </para>
<para>You can use the data-bound controls that are provided with ASP.NET, including <see cref="T:System.Web.UI.WebControls.GridView" />, <see cref="T:System.Web.UI.WebControls.DetailsView" />, and <see cref="T:System.Web.UI.WebControls.TreeView" />, to perform most Web development tasks that involve displaying data. In scenarios in which these controls do not provide the functionality you need, you can inherit from the base <see cref="T:System.Web.UI.WebControls.DataBoundControl" /> and <see cref="T:System.Web.UI.WebControls.HierarchicalDataBoundControl" /> classes to implement your own custom data source control.</para>
<para>While any class that supports the DataSource and DataSourceID properties and the DataBind method is a data-bound control, most ASP.NET data-bound controls extend the abstract <see cref="T:System.Web.UI.WebControls.BaseDataBoundControl" /> and <see cref="T:System.Web.UI.WebControls.DataBoundControl" /> classes. Notable exceptions include <see cref="T:System.Web.UI.WebControls.DataGrid" />, <see cref="T:System.Web.UI.WebControls.Repeater" />, and the <see cref="T:System.Web.UI.WebControls.DropDownList" /> controls. For more information about data binding, see <format type="text/html"><a href="f9219396-a0fa-481f-894d-e3d9c67d64f2">Accessing Data with ASP.NET</a></format>.</para>

<para>The <see cref="T:System.Web.UI.WebControls.BaseDataBoundControl" /> class overrides the <see cref="M:System.Web.UI.WebControls.BaseDataBoundControl.DataBind" /> method to identify the data source that the data-bound control binds to and builds the appropriate control trees. When resolving the data source, the data source identified by the <see cref="P:System.Web.UI.WebControls.BaseDataBoundControl.DataSourceID" /> property takes precedence. If <see cref="P:System.Web.UI.WebControls.BaseDataBoundControl.DataSourceID" /> is not set, the object identified by the <see cref="P:System.Web.UI.WebControls.BaseDataBoundControl.DataSource" /> property is used. </para>

<para>The <see cref="M:System.Web.UI.WebControls.BaseDataBoundControl.OnPagePreLoad(System.Object,System.EventArgs)" /> event handler is used to control when data binding occurs within the life cycle of the page. It does this by setting the internal initialized state of the data-bound control. Because the control's initialized state is set during the <see cref="E:System.Web.UI.Page.PreLoad" /> phase of the page's lifecycle, the <see cref="M:System.Web.UI.WebControls.BaseDataBoundControl.OnDataPropertyChanged" /> event handler is called any time a data property of the control is changed after that phase, to signal that the control must re-bind to its data before rendering. </para>
