It may as well be the easier solution. I've seen weird behaviors with combos in a grid, where the rowsource of the combo was dependent on a listbox, and having one combo for each of the possible values coming from the listbox actually made those problems go away.

I wouldn't be surprised if it worked the same for checkboxes. They seem to have their own quirks in some grids, so maybe the same cure would work.
