Drag n drop to layout panel, addition to tree-grid


I have two panels in a certain layout, each contains tree-grid. I need to drag n drop between each tree-grid, which I implement just fine. But sometimes, the tree folder is pretty short, so my user like to be able to drag n drop to whole panel, which means rest of tree-grid area inside of the panel. I can pre-define which row would end up too, so target row is not issue, I just need your help to make the panel ( other than tree-grid) become drag n drop target, and catch the drag n drop event.

Thank you.[/b]
