Remarks

Raising an event invokes the event handler through a delegate. The OnFrameChanged 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 OnFrameChanged in a derived class, be sure to call the base class's OnFrameChanged method so that registered delegates receive the event.

Requirements

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Vista, and Windows Server 2003 family
