Remarks
Raising an event invokes the event handler through a delegate. The OnEraseBackground 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.
Note to Inheritors: When overriding OnEraseBackground in a derived class, be sure to call the base class's OnEraseBackground method so that registered delegates receive the event.
