Binds a data source to the invoked server control and all its child controls.
Assembly: System.Web (in System.Web.dll)
The BaseDataBoundControl class overrides the 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 DataSourceID property takes precedence. If DataSourceID is not set, the object identified by the DataSource property is used.
The DataBind method is sealed on all ASP.NET data-bound controls derived from BaseDataBoundControl. Data-bound controls derived from the DataBoundControl and HierarchicalDataBoundControl classes should override the PerformDataBinding method instead of the DataBind method to bind data. If DataBind is overridden, the OnDataBinding and OnDataBound events are raised out of order.
