Public Delegate Sub AppointmentItemOperationEventHandler( sender As Object, e As AppointmentItemOperationEventArgs )
The event source. This parameter identifies the SchedulerControl control which raised the event.
A AppointmentItemOperationEventArgs object which contains event data.
When creating a AppointmentItemOperationEventHandler 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 about event handler delegates, see Events and Delegates in MSDN.
