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 BaseDataBoundControl control class, which defines the base data-bound control functionality.

You can use the data-bound controls that are provided with ASP.NET, including GridView, DetailsView, and 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 DataBoundControl and HierarchicalDataBoundControl classes to implement your own custom data source control.

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 BaseDataBoundControl and DataBoundControl classes. Notable exceptions include DataGrid, Repeater, and the DropDownList controls. For more information about data binding, see Web Page Data Binding Techniques.
