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.

By default, end-users are allowed to delete appointments by using UI elements. Use the AllowAppointmentDelete property to control the availability of such functionality to end-users with respect to an appointment’s type. For instance, if this property allows appointments of all types to be deleted (the property is set to UsedAppointmentType.All), end-users can delete an appointment either by selecting the Delete item in a popup menu invoked for the desired appointment, pressing the Delete keyboard key when the desired appointment is selected or clicking the Delete button within the appointment’s Edit Appointment dialog.


If the AllowAppointmentDelete property is set to UsedAppointmentType.Custom, then whether an end-user is allowed to delete appointments or not is decided in the SchedulerControl.AllowAppointmentDelete event handler.
