I thought that should work too but it didn't. As I explained to David tonight, it appears that the field's data value isn't being evaluated at the proper level. It's as if the entire column is assigned the display value of the most recently accessed row. That's why I think the solution, if there is one, will use a dynamic property which forces re-evaluation at the "cell" level. Caroline's suggestion to use DynamicCurrentControl in the column seems like it should work. I haven't had time to check it out yet.
