Remarks
The OnDataSourceViewChanged method notifies a data-bound control that the underlying data source has changed and that the control should rebind and perform any necessary work. Typically, the OnDataSourceViewChanged method is called when a property of the data source view has changed.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnDataSourceViewChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnDataSourceViewChanged(EventArgs) in a derived class, be sure to call the base class's OnDataSourceViewChanged(EventArgs) method so that registered delegates receive the event.
