Thanks Cathi,

That did the trick. I had been trying to get this to work a coupla weeks ago, and that was before I had known about the TreeView.GetNodeAt() method, which was probably the only piece of the puzzle that I was missing at the time. And, luckily, this is generic enough that I can probably put it in a TreeView baseclass and not have to worry about it again.

But, I'm curious about one thing. It's interesting that the X,Y coordinates of MouseEventArgs is more accurate (if that's the correct description) than the X,Y coordinates of the DragEventArgs. In a similar type of operation with drag/drop (in fact, you may have been the one to post the code for me), I had to take the X,Y coordinates and convert that to a Point and use GetNodeAt(Point) instead of GetNodeAt(X,Y). I had thought it was an extraneous step when I originally was trying this drag/drop code, and so I tried using the X,Y directly, but it would never work. Any ideas why these behave differently? And how to know *when* to use X,Y and *when* you have to do the point conversion???

TIA,
~~Bonnie

>>Hey All,

>>I have a TreeView control on a Windows Form. I also have a ContextMenu to pop-up when the user right-clicks on the Tree. No problem, it all works fine ... except for one little thing. If the user right-clicks on a node in the tree other than the one that's selected, when the ContextMenu pops ups, it will appear to them (temporarily) as if that node is selected, when in fact it is not. As soon as an item from the pop-up menu is selected, the highlight goes back to the real selected node (in fact, the TreeView.Selected node never changes, just the highlight).
