swap dropdown

Hi everyone,
here i'm swaping the dropdown values with the value last selected.

code:

        ListItem selected = drpdwn_Form.SelectedItem;
        if (selected == null)
            return;
        drpdwn_Form.Items.Remove(selected);
        drpdwn_Form.Items.Insert(0, selected);


Have a nice day... 'N happy Coding :)
