Raymond, I've followed this and finally decided it was time to give it a try myself. I'm a little confused. At what point exactly are you doing step #4?

You can't be doing it in the load of the form since the grid isn't instantiated yet, and you can't do it in the designer since you can't get at the column properties in the grid. That really only leaves the grid's init, but you don't say, so I'm only guessing.

If you are doing it in the grid's init, then I can't reproduce the problem. It works perfectly for me.

If I'm making bad assumptions, let me know. Maybe I'm not really reproducing exactly what you are doing.
