- Drag-and-drop operations managed automatically or set programmatically
- Limitations
DndTarget (Property) In french: DndCible
Drag and Drop Some controls of WINDEV and WEBDEV can manage drag-and-drop operations automatically: simply check the corresponding option in the "Details" tab of the control description. A control can be defined as source or target of a drag-and-drop operation. Drag-and-drop operations are automatically 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.
