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 AppointmentDrop event to manage, with the drag-and-drop action, appointments within the Scheduler control. Information, which is provided by the event’s argument properties, allows you to deny, cancel or handle specifically the event.

For instance, you have access to the appointment before dragging (the AppointmentDragEventArgs.SourceAppointment property), to the time interval where the appointment was dropped (the AppointmentDragEventArgs.HitInterval property), the resource associated with a new appointment location (the AppointmentDragEventArgs.HitResource property). The AppointmentDragEventArgs.NewAppointmentResourceIds property can be used for assignment of resources to a relocated appointment.
