>I never used combobox with Int field because it is supposed to work with character data only. Working with Int field comes from older versions of FoxPro and left for compartibility. It is not recommended to use this feature of combobox at all, because it is also confusing and less maintenable for application solutions (Int field is populated by comnbobox differently). Can you give sample of use-cases for such approach? Never had it.
