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