I have a DataGridView control with the FullRowSelect SelectionMode, chosen (MultiSelect=False). So I select a row and all cells in that row go blue.

I don't want the left-hand cell to go blue when I select a row, as this cell is colour-coded (background colour of cell is either red or green and I want the cell to stay that colour even when selected)

Does anyone have any idea which event to handle to prevent this?

Thanks
