parse dropdown lists

Question

I have my form made and data being pulled into the dropdownlists. Now I would like to go thru dropdownlists and search for data that might be different and highlight it for the user. I have about 30 in the form so I need this to be compact/modular. More specifically for an example: I have a dropdownlist that lists all the names for a product found in the database, they should be the same, but if they arent I would like to put a star next to the dropdown so the user should look at it and choose the correct answer for submitting. So I should set a label next to the pulldown that I can fill with a *, but how should I go thru the dropdowns to compare the data?

The only way I can think of is to go through each of the items in the drop down. But you would have to do this each time the items in the drop down change. You can check if the drop down is empty by (dropDown.Items.Count == 0). But if your drop down also allows the user to enter text (i.e. the drop down is a combox) then I think you would also need to make sure that the text of the drop down is empty (dropDowm.Text == String.Empty). Sorry I couldn't be more specific
