Event Data

The AppointmentChanging 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.

Remarks

The AppointmentChanging event is raised when changing an appointment’s property. The appointment whose property is changed is identified by the event parameter’s PersistentObjectEventArgs.Object property. Set the PersistentObjectCancelEventArgs.Cancel to true to roll back changes and cancel the operation.

Note

Do not modify the appointment’s data source or data binding within this event handler. It results in the current appointment being disposed of, and consequently, an unhandled exception occurs.
