A method that will handle the ASPxScheduler.PopupMenuShowing event.
public delegate void PopupMenuShowingEventHandler( object sender, PopupMenuShowingEventArgs e );
Public Delegate Sub PopupMenuShowingEventHandler( sender As Object, e As PopupMenuShowingEventArgs )
The event sender (typically an ASPxScheduler control).
A PopupMenuShowingEventArgs object that contains event data.
When creating a PopupMenuShowingEventHandler delegate, you identify a method that will handle corresponding events. To associate an event with your event handler, add a delegate instance to the 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.
