I have a method that calls and load my combobox. Once the call is made, i then added "All" to be first on the combobox. Unfortunately when this is added to the list, "All" takes the index of 0 which messes everything up. The selectedindex should be "a" as from the table. Is there a way to set "All" to be -1 as the index? What might be the best way to still have "a" as an index of 0 instead of an index of 1?

```
private void Load()
{
    List<string> all = dataSource.GetAll();

    if (all.Count > 1)
    {
        cbAll.Items.Clear();
        cbAll.BeginUpdate();

            cbAll.Items.Add("All");

            foreach (var item in all)
            {
                cbAll.Items.Add(item);
            }
            cbAll.SelectedIndex = 0;
    }
}

```

table ITEM result

```
0 -- a
1 -- b
2 -- c
3 -- d

```
