public event PersistentObjectCancelEventHandler AppointmentDependencyInserting

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.


The AppointmentDependencyInserting event is raised before an appointment dependency is added to the SchedulerStorage.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.


To validate appointment insertion, you can get properties of the appointment being inserted by casting the e.Object parameter to the AppointmentDependency type.
