Remarks
Handle this event to perform any actions prior to the Confirm Delete dialog being shown. For instance, a custom dialog can be substituted in place of the standard dialog (and the ShowFormEventArgs.Handled property set to true.)
This dialog can be invoked either by an end-user, or via the SchedulerControl.ShowDeleteRecurrentAppointmentForm method. The QueryResult property enables you to specify whether the entire appointment series should be edited, or only the selected appointment.
