If specified, the OnClientRecurrenceExceptionsRemoving client-side event handler is called when recurrence exceptions are about to be removed via Web Service call. In the case of server-side binding, the event will not be raised. When client-side binding is used, the event will be raised when the user chooses to remove the recurrence exceptions of a given series through the advanced form.
Two parameters are passed to the handler:
sender - the scheduler client object;
eventArgs with two properties:
get_appointment() -the master appointment that represents the recurrence series.
set_cancel() - set to true cancel the operation.
This event can be cancelled.
