>If you look at the grid with the debugger, what does the input mask show? Is there a chance it is being changed by your framework somewhere? Also, are you sure the fields in the table/cursor populating the grid are truly integers? Look at them with Browse to check.

Thanks! It turned out that there was code in one of the parent classes to assign an input mask for numeric data. Now it's fine.
