SchedulerDataStorage.AppointmentDependencyInserting Event
Allows you to cancel the insertion of an appointment dependency.
Namespace: DevExpress.XtraScheduler
Assembly: DevExpress.XtraScheduler.v24.1.dll
NuGet Package: DevExpress.Win.Scheduler
Declaration
Event Data
The AppointmentDependencyInserting 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 AppointmentDependencyInserting event is raised before an appointment dependency is added to the SchedulerDataStorage.AppointmentDependencies collection and allows you to cancel the operation. The event parameter’s PersistentObjectEventArgs.Object property allows identification of the appointment dependency. To prevent it from being added, set the PersistentObjectCancelEventArgs.Cancel property to true.
Note
To validate appointment insertion, you can get properties of the appointment being inserted by casting the e.Object parameter to the AppointmentDependency type.
