I do have an OnDrawCell event - the problem is that it is not getting triggered... If I change a string it gets triggered - calling repaint etc must do some sort of check for a modified state (guessing). I haven't done much on this yet as I spent yesterday Installing D7 and migrating applications (and their components + updating the doc on doing this etc.).
