DataColumn with Expression is null in xsd designer

    I have a simple datatable created in the vwd xsd designer, and have
    added one additional column that has an expression set to the
    difference of two columns (col1 - col2). Using "Preview" on the select
    methods, the expression column works fine. When an object data source
    is set to the datatable, the expression column always returns null (or
    the default). Is there an additional property or method that needs to
    be called for a object data source or gridview to run the expression
    stored in the datacolumn?
