drag n drop betweet two listbox cells?

I have a cell in one listbox and I want to drag and drop it’s contents into the other listbox cell.
Help?
Nothing special in the cells just text… Copy and past would work… but… that’s not as elegant as drag n drop.

Theres an example project with exactly the code you need
See Examples > Desktop DragAndDrop > ListBoxesDragAndDrop
