Hi Hans,

> It seems the when clause doesnt prevent you from clicking on a column and having it change color.

It's the textbox that has the When method. Clicking into the column activates the column and sets the focus to the active control in the column. If the control refuses focus, the focus will remain with the column. Unfortunately, the column only has a SetFocus method, but no corresponding GetFocus event. You could use the AfterRowColChanged event of the grid to move the focus to the next column when the user activated the wrong one.
