        Bind_DataGridView.DataSource = dSet.Tables[0];
        MainTableGrid.DataSource = Bind_DataGridView.DataSource;
        MainTableGrid.Refresh();
        MainTableGrid.Parent.Refresh(); 

Are you getting data back from your query?

If not add a comma between FIELDNAME and BS_FIELDF in your SQL statement.
