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 can drag the time boundaries of an appointment to change the appointment’s start or end times. Use the AllowAppointmentResize property to control the availability of such functionality to end-users, with respect to an appointment’s specific type.


If the AllowAppointmentResize property is set to UsedAppointmentType.Custom, then whether an end-user is allowed to change the time boundaries of appointments or not, is decided in the SchedulerControl.AllowAppointmentResize event handler.
