>i have a combobox that's populated using a foreach loop through a list object. There are three items from the database that get added to the list: id, paycode, description. The only way I know how to do it is by creating a string. But what I need is to separate the id into it's own column, so we can use it to do a lookup through a stored procedure. Can anyone tell me how this is done?

Can you use an object for the ListBox binding ? eg:

   public class Thing
    {
        public int Id { get; set; }
        public int PayCode { get; set; }
        public string Description { get; set; }
    }

then:

List<Thing>  things = new List<Thing>();
            things.Add(new Thing{Id=1,PayCode=2,Description="One Thing"});
            things.Add(new Thing { Id = 2, PayCode = 3, Description = "Another Thing" });
            listBox1.DataSource = things;
            listBox1.DisplayMember = "Description";

When you need to see which item is selected:

Thing  thing = (Thing) listBox1.SelectedItem;
