I have a form that looks like a keyboard, on the form is about 3 panels. Depending on what the user is doing determines what panel is visible and then, what textboxes are available. The idea being hit clicks on name text field lets say, and then hits the a, b,c, etc... on the keyboard. I need to know what field he just came from so I know what fields to put the keyboard items into. I hope that makes sense.
