    Hi guys,

    Roomno is already string and its value is from sql query. your code has no error but i having the same error during runtime.
    i tried to change btn.backcolor to btn101.backcolor and it works well with the button,
    but when i try to change it back with your code it gives me the same error (NullReferenceException was Unhandled).
    i have buttons named btn101 to btn819.



    hope u can help me.
