In this online example...
Click and drag an item from TreeView1 and drop it on an empty space on the page. (But not on the other tree, input, or datagrid) See how it stays highlighted?
Is there any way to un-highlight the node in that situation?
The reason is because it may be confusing to the user to "cancel" the drop by dropping the node outside of the tree, but low and behold, it's still highlighted.
Not a huge deal but would be icing on the cake.
