Hello all. I am trying to drop a custom container class into a grid column and have it replace the standard textbox. I am able to get this to work just fine but when you try to use the arrow keys to navigate from cell to cell the up and down keys do not work correctly. The up key moves highlight to the left and right key moves highlight to the right. What am I missing? Is it possible to get full navigation with a custom container control? Any and all responses is appreciated.

ps. This is with sparse set to .f.
