Remarks

The PersistentObjectCancelEventArgs class introduces a PersistentObjectCancelEventArgs.Cancel property which allows the operation associated with the corresponding event handler to be canceled. The processed persistent object is identified by the PersistentObjectEventArgs.Object property

An instance of the PersistentObjectCancelEventArgs class with appropriate settings is automatically created and passed to the corresponding event’s handler.
