InvalidateEventHandler Delegate

Represents the method that will handle the Invalidated event of a Control.

[Visual Basic]
Public Delegate Sub InvalidateEventHandler( _
   ByVal sender As Object, _
   ByVal e As InvalidateEventArgs _
public delegate void InvalidateEventHandler(
   object sender,
   InvalidateEventArgs e
public __gc __delegate void InvalidateEventHandler(
   Object* sender,
   InvalidateEventArgs* e

[JScript] In JScript, you can use the delegates in the .NET Framework, but you cannot define your own.

Parameters [Visual Basic, C#, C++]

The declaration of your event handler must have the same parameters as the InvalidateEventHandler delegate declaration.

The source of the event.
An InvalidateEventArgs that contains the event data.


When you create an InvalidateEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about handling events with delegates, see Events and Delegates.
