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.

Use the AllowDisplayAppointmentForm property to specify whether the Edit Appointment dialog should be invoked when an end-user double-clicks an existing appointment. To prevent end-users from editing existing appointments via this dialog, set the AllowDisplayAppointmentForm property value to AllowDisplayAppointmentForm.Never.


Note that even if the AllowDisplayAppointmentForm property is set to Never, an end-user may invoke the Edit Appointment dialog by double-clicking an empty time cell to create a new appointment.

To get an example of using the OptionsCustomization.Allow* properties and handling the SchedulerControl.Allow* events, refer to How to: Set End-User Restrictions (legacy).
