>Is there any way to display different colors of different items in a combobox based on a condition instead of changing all items in the combobox object?

You may even change fonts if your listbox or combo is based on a colorful popup, but you'll lose some other stuff - multiselect, incremental search or some like that. Not sure what stops working for some rowsource types.

Haven't tried that myself, but I know it's been done.
