There is a difference between " " and "". In your check, you should check for the length of the trimmed value rather than checking for " ". (DD_jobno.DataValueField.Trim().Length() in C# syntax) Your check will only be true if the field contains a single space. If there is more than one or less than one, your test will fail.
