You are viewing documentation for the legacy WPF Scheduler control. If you’re starting a new project, we strongly recommend that you use a new control declared in the DevExpress.Xpf.Scheduling namespace. If you decide to upgrade an existing project in order to switch to the updated scheduler control, see the Migration Guidelines document.

Handle the AllowAppointmentDelete event to manually decide whether to allow an end-user to delete an appointment or not. Note that the appointment to delete can be accessed via the AppointmentEventArgs.Appointment property. To prevent an appointment from being deleted, set the AppointmentOperationEventArgs.Allow property to false.


The AllowAppointmentDelete event is fired only if the OptionsCustomization.AllowAppointmentDelete property is set to UsedAppointmentType.Custom.
