By default, RadScheduler allows you to reorder the Appointments into the view either in bound or unbound mode. It is accomplished by the AppointmentDraggingBehavior. If you need to customize the default drag and drop behavior you can handle the relevant events. As a descendant of RadDragDropService, AppointmentDraggingBehavior handles the whole drag and drop operation. The PreviewDragOver event allows you to control on what targets the appointment being dragged can be dropped on. The PreviewDragDrop event allows you to get a handle on all the aspects of the drag and drop operation, the source (drag) RadScheduler, the destination (target) control, as well as the AppointmentElement being dragged. This is where we will initiate the actual physical move of the appointment(s) from one scheduler to the target control. A sample implementation is demonstrated in the Drag and Drop Using RadDragDropService help article.
