protected:
 virtual System::Web::UI::IDataSource ^ GetDataSource();

protected virtual System.Web.UI.IDataSource GetDataSource();

abstract member GetDataSource : unit -> System.Web.UI.IDataSource
override this.GetDataSource : unit -> System.Web.UI.IDataSource

Protected Overridable Function GetDataSource () As IDataSource

Returns

IDataSource

An IDataSource that represents the data source identified by DataSourceID.

Exceptions

HttpException

The control identified by the DataSourceID property does not exist in the current container.

-or-

The control identified by the DataSourceID property does not implement the IDataSource interface.

Remarks

The GetData method calls the GetDataSource method internally. A valid IDataSource instance is retrieved by these two methods and is cached by the DataBoundControl object until the OnDataPropertyChanged method signals that the data source has changed.
