The DataSourceView.OnDataSourceViewChanged(EventArgs) 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 DataSourceView.OnDataSourceViewChanged(EventArgs) 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 Raising an Event.

The DataSourceView.OnDataSourceViewChanged(EventArgs) 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.
