Hi, the gridview has an OnRowDataBound event. In that event you can do your thing like:

Int32 Total = 0;
Int32 ValueCol1 = 0;
Int32 ValueCol2 = 0;
Int32 Together = 0;
if (e.Row.RowType.Equals(DataControlRowType.DataRow))
            {

                try
                {
                    DataTable tabel = (DataTable)myGridView.DataSource;
                    ValueCol1 = Convert.ToInt32(tabel.Rows[e.Row.RowIndex].ItemArray[0]);
                    ValueCol2 = Convert.ToInt32(tabel.Rows[e.Row.RowIndex].ItemArray[1]);
                    Together = ValueCol1 * ValueCol2;
                    Total += Together;
                }
                catch (Exception err)
                {
                    lblError.Text = err.Message;
                }
            }
if (e.Row.RowType.Equals(DataControlRowType.Footer))
{
       e.Row.Cells[2].Text = Total.ToString();
}

for: ValueCol1 = Convert.ToInt32(tabel.Rows[e.Row.RowIndex].ItemArray[0]); find the appropriate field in the ItemArray. Field[0] is the first displayed field
