Hi All,
 
I am writing an app where I need to make extensive use of drag and drop
using treeviews.
 
I am aiming for the "Explorer Style" drag and drop, where as you drag the
folder over other folders it 
highlights the folder you are hovering over and then when you "drop" it adds
it to the highlighted folder.
 
I have tried several methods but to no avail. 
Does anybody have any clue as to how I might accomplish this.
 
Any help would be greatly appreciated.
 
Regards
 
Graeme Melville
