Represents the method that will handle the System.WinForms.RichControl.Help event of a RichControl.
[Visual Basic] Public Delegate Sub HelpEventHandler( _ ByVal sender As Object, _ ByVal hlpevent As HelpEventArgs _ ) [C#] public delegate void HelpEventHandler( object sender, HelpEventArgs hlpevent ); [C++] public __gc __delegate void HelpEventHandler( Object* sender, HelpEventArgs* hlpevent );
[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 HelpEventHandler delegate declaration.
When you create a HelpEventHandler 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.
