Remarks

Important

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 share the schedule time between two or more appointments. Use the AllowAppointmentConflicts property to control the availability of such functionality to end-users.

If this property is set to AppointmentConflictsMode.Allowed, the time interval of two or more appointments can intersect and sharing the schedule time between the appointments is allowed. Set the AllowAppointmentConflicts property to AppointmentConflictsMode.Forbidden to prevent scheduling (or rescheduling) of two or more appointments for the same time.

Note

If the AllowAppointmentConflicts property is set to AppointmentConflictsMode.Custom, then whether an end-user is allowed to share the schedule time between two or more appointments or not is decided in the SchedulerControl.AllowAppointmentConflicts event handler.
