How do I hide the focus rectangle?

I have some columns that contain images (special checkboxes,etc ) and I need to allow the user to click on the cell and change the image. I have that working but the focus rectangle is a little distracting in this use. How can I turn it off or set its attributes somehow to be invisible? Thanks,

There is a ShowCurrentCellBorderBehavior property that you can use to always hide this currentcell border. You would probably want to set this to HideAlways if one of your special cells is the target of a CurrentCell.MoveTo (try handling CurrentCellMoving), and then set it to some other setting if the target cell is not one of your special cells.
