I have a datagridview with a datagridviewcheckboxcolumn. I currently have this as a 3 state option so you get checked, unchecked and the filled square. For the 3rd state, I'd rather the cell be completely blank.

Is there a way to hide the square all together so you'd see checked, unchecked, totally blank, as shown here:
