I'm trying to set up a drag'n drop between a grid and a treeview.
I saw the example and it works.

The first problem is that I want to detect on the drop event if the user pressed Ctrl key.
For that I use the "data.event.ctrlKey" but it is always set to false!

The second problem is how to change the label displayed during the drag'n drop.
For example, if the user not press the ctrl key I want to display "copy xxx" and if he press the key I want to display "move xxx".

How can I do that?

Thank you,
