I have been Googling for thumbnails, opaque images, etc and found nothing. I think I'm just searching for the wrong thing...
I have two listboxes and you can drag from the left list to the right. The left list is composed of a bunch of user controls... what I want is while the user is dragging to show a small thumbnail/image of the user control that they are dragging. Like when you drag a file in Windows, you can see a thumbnail of the file you're dragging.
What is this called? Just the name would be great! Any links would also be appreciated, but if I know what I'm searching for I should be okay... thanks.
