Represents the method that will handle the Invalidate event of a RichControl.
[Visual Basic] Public Delegate Sub InvalidateEventHandler( _ ByVal sender As Object, _ ByVal e As InvalidateEventArgs _ ) [C#] public delegate void InvalidateEventHandler( object sender, InvalidateEventArgs e ); [C++] public __gc __delegate void InvalidateEventHandler( Object* sender, InvalidateEventArgs* e );
[JScript] In JScript, you can use the delegates in the NGWS frameworks, but you cannot define your own.
The declaration of your event-handling method must have the same parameters as the InvalidateEventHandler delegate declaration.
When you create a InvalidateEventHandler delegate, you identify the method that will handle the event. To associate the event with your event-handling method, add an instance of the delegate to the event. The event-handling method is called whenever the event occurs, unless you remove the delegate. For more information about handling events with delegates, see TBD.
