Hi, I have a combo box that takes its values from a database. I need to make unique items in the combobox. I could do this in database part, but I need other attributes of values. Let me explain:
There is Surgery table in my database with id,name and clinic attributes. In combobox, I want to display unique clinic names. At the same time i want to hold multiple surgeries in the clinic in another combobox.
To sum up, How can I display unique attributes of a List.
