public delegate void CustomHeaderButtonEventHandler( object sender, CustomHeaderButtonEventArgs e );
Public Delegate Sub CustomHeaderButtonEventHandler( sender As Object, e As CustomHeaderButtonEventArgs )
The event source. Identifies the TabbedView object that raised the event.
A CustomHeaderButtonEventArgs object that contains the event data.
When you create a CustomHeaderButtonEventHandler delegate, you need to identify the method that will handle the corresponding event. To associate an event with your event handler, add a delegate instance to this event. The event handler is called whenever the event occurs unless you remove the delegate. For more information about event handler delegates, see Events and Delegates in MSDN.
