public delegate void RibbonPageGroupEventHandler( object sender, RibbonPageGroupEventArgs e );
Public Delegate Sub RibbonPageGroupEventHandler( sender As Object, e As RibbonPageGroupEventArgs )
The event source.
A RibbonPageGroupEventArgs object which contains event data.
When creating a RibbonPageGroupEventHandler delegate, you 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 on event handler delegates, see Events and Delegates in MSDN.
