[<BrowsableAttribute(false)>]
override AllowDrop : bool with get, set

Property Value

Type: System.Boolean

true if drag-and-drop is enabled in the control; otherwise, false.

The following code example demonstrates how to perform drag-and-drop operations using a ListBox control that contains items to drop into a RichTextBox control. The constructor of the form sets the AllowDrop property to true to enable drag-and-drop operations to occur in the RichTextBox. The example uses the MouseDown event of the ListBox to start the drag operation by calling the DoDragDrop method. The example uses the DragEnter event to determine if an item being dragged into the RichTextBox is a valid data type. The DragDrop event performs the actual dropping of a dragged item into the RichTextBox control at the current cursor location within the RichTextBox. This example requires that the DragDrop and DragEnter events have been connected to the event handlers defined in the example.
