GridLayout Events
Events in the View Designer
● onDrop
Assignment of the action to be executed when the user moves an entry or multiple entries in the GridLayout by means of Drag&Drop.
You can only use this event in dynamic progamming. Therefore, create a DragSourceInfo and a DropTargetInfo, append these to the GridData, and set the event dynamically.
Note that Drag&Drop is only possible with a one-column GridLayout.
