Why? What do you want to achieve with that? It is "regular" drag/drop functionality of something unusual? What have you tried so far?

Thanks for your comment. In my scenario, i have stack panel and item into stack panel. When i drag and drop item, the item will swap position. I implement 2 function Preview_Drop and Preview_DragOver. But when i move item outside stack bounds, how can i detected item is drop outside or inside stackpanel? Thanks
