Hi Victor,
As for GridView(or ASP.NET 1.1 DataGrid), you can certainly add subtotal
calculation feature. There several approachs on this:
** using inline function to sum up the values in each row
** using RowDataBound event and use code in codebehind to calculate
here are some web articles demonstrate on this:
