Event Data

The AppointmentDeleting event's data class is PersistentObjectCancelEventArgs. The following properties provide information specific to this event:

Property Description
Cancel Gets or sets whether to cancel the operation.
Object Gets the persistent object (appointment, resource or appointment dependency) for which the event occurs. Inherited from PersistentObjectEventArgs.


The AppointmentDeleting event is raised before an appointment is deleted and allows you to cancel the deletion of an appointment. The event parameter's PersistentObjectEventArgs.Object property allows the processed appointment to be identified. To prevent it from being deleted, set the PersistentObjectCancelEventArgs.Cancel property to true.


Do not modify a persistent object for which the event is raised in the event handler's code.
