Drag and Drop

For some types of controls, WINDEV and WEBDEV propose an automatic management of Drag and Drop: to do so, check the corresponding option in the "Details" tab of the control description. Then, a control can be defined as source or target of Drag and Drop.
The automatic Drag and Drop is available:
  • WINDEV for the edit controls, the list boxes, the listviews, the treeviews.
  • Versions 17 and later
    WEBDEV - Server code for the Upload controls, the static controls, the buttons, the links, the images, the formatted static controls, the list boxes and the combo boxes.
    New in version 17
    WEBDEV - Server code for the Upload controls, the static controls, the buttons, the links, the images, the formatted static controls, the list boxes and the combo boxes.
    WEBDEV - Server code for the Upload controls, the static controls, the buttons, the links, the images, the formatted static controls, the list boxes and the combo boxes.
During a Programmed Drag and Drop, ..DndSource and ..DndTarget are used to define the source and target controls of Drag and Drop.
..DndTarget is used to find out and modify the behavior of a control during Drag and Drop. This control will be defined as target for "Drag and Drop", which means that "Drag and Drop" will be performed toward this control.
