Raises the BeforeItemCheck event.
[Visual Basic] Overridable Protected Sub OnBeforeItemCheck( _ ByVal e As ListViewItemCancelEventArgs _ ) [C#] protected virtual void OnBeforeItemCheck( ListViewItemCancelEventArgs e ); [C++] protected: virtual void OnBeforeItemCheck( ListViewItemCancelEventArgs* e );
Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.
The OnBeforeItemCheck 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 OnBeforeItemCheck in a derived class, be sure to call the base class's OnBeforeItemCheck method so that registered delegates receive the event.
