The EditRecurrentAppointmentFormShowing event is raised only if the SchedulerOptionsBehaviorBase.RecurrentAppointmentEditAction is set to the RecurrentAppointmentAction.Ask value. Handle this event to perform any actions prior to the Open Recurring Item dialog being shown. You can substitute the default dialog with a custom one and set the ShowFormEventArgs.Handled property to true to prevent default event handling.
This dialog can be invoked either by an end-user, or via the SchedulerControl.ShowEditRecurrentAppointmentForm method. The QueryResult property enables you to specify whether the entire appointment series should be edited or only the selected appointment.
