An EventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate.

The OnSourceRectangleChanged 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 OnSourceRectangleChanged in a derived class, be sure to call the base class's OnSourceRectangleChanged method so that registered delegates receive the event.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
