# AppointmentDraggingBehavior

**RadScheduler** handles the whole drag and drop operation by its **AppointmentDraggingBehavior**. It exposes the following public properties, methods and events:

## Properties

## Events specific only for the AppointmentDraggingBehavior

| Event                   | Description                              |
| ----------------------- | ---------------------------------------- |
| **FeedbackCreating**    | Occurs when the feedback is creating.    |
| **FeedbackInitialized** | Occurs when the feedback is initialized. |
| **AppointmentMoving**   | Occurs when an appointment is moving.    |
| **AppointmentMoved**    | Occurs when an appointment is moved.     |
| **AppointmentDropping** | Occurs when drag drop is finishing.      |
| **AppointmentDropped**  | Occurs when drag drop has finished.      |

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](https://www.telerik.com/products/winforms/documentation/telerik-presentation-framework/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](https://www.telerik.com/products/winforms/documentation/controls/scheduler/drag-and-drop/drag-and-drop-using-raddragdropservice) help article.
