Allows you to cancel an appointment deletion.
Namespace: DevExpress.XtraScheduler
Assembly: DevExpress.XtraScheduler.v23.2.Core.dll
NuGet Package: DevExpress.Scheduler.Core
Declaration
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. |
Remarks
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 returns the appointment being deleted. You should cast it to the Appointment type to examine its properties. To prevent it from being deleted, set the PersistentObjectCancelEventArgs.Cancel property to true.
Important
Do not modify a persistent object for which the event is raised in the event handler’s code.
