DndTarget (Property) In french: DndCible
Drag and Drop For certain field types, WINDEV and WEBDEV offer a manage drag-and-drop operations automatically: simply check the corresponding option in the "Detail" tab of the field description. A control can be defined as source or target of a drag-and-drop operation. Automatic Drag and Drop is available:  for Upload, Static, Button, Link, Image, formatted text, List Box and Combo Box controls.
In a drag-and-drop operations set programmatically, the DndSource and DndTarget properties are used to define the source and target controls. The DndTarget property determines and changes how a control behaves in a drag-and-drop operation. The control will be defined as the drop target, i.e., the control where the dragged items will be dropped.
