public delegate void SchedulerCallbackCommandEventHandler( object sender, SchedulerCallbackCommandEventArgs e );
Public Delegate Sub SchedulerCallbackCommandEventHandler( sender As Object, e As SchedulerCallbackCommandEventArgs )
The ASPxScheduler control which fires the event.
A SchedulerCallbackCommandEventArgs object containing event data.
When creating a SchedulerCallbackCommandEventHandler 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.
