even when I add listItems menually like this :

cboCities.Items.Add(new MobileListItem ( "ten" ,"10"));

without using of values that come from stored procedure , I'm still
can't do this !!! i mean cboCities.Selection = null inside the
go_click event . It's driving me mad ! The WML is generated by VS.NET
.. I don't see anything wrong in it . Do you have any other ideas ?
Thanks a lot for the assistance !
