# OnClientRecurrenceExceptionsRemoving

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.
