Namespace: DevExpress.Xpf.Scheduler

Assembly: DevExpress.Xpf.Scheduler.v14.2.dll

Declaration

C#

public event PersistentObjectCancelEventHandler AppointmentChanging

VB.NET

Public Event AppointmentChanging As PersistentObjectCancelEventHandler

Event Data

The AppointmentChanging event's handler receives an argument of the PersistentObjectCancelEventArgs type. The following properties provide information specific to this event:

Property	Description
Cancel	Gets or sets whether the operation performed on the processed event should be canceled.
Object	Gets the persistent object for which the event was raised. 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.
