You can just use row data bound event of the datagrid list view or the control your using. and form there you can access entire row. then calculate the values and display it in the last column

well i finish it with this code below put in datarowbound.

C#

protected void GridView1_RowDataBound1(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
            {
                total = 0;
                int intex = GetColumnIndexByName(e.Row, "Category");
                if (e.Row.Cells[intex].Text == "Class")
                {
                    var jo = 1;
                    var ro = 2;
                    while (jo <= days)
                    {
                        if (e.Row.Cells[ro].Text == " ")
                        {
                            e.Row.Cells[ro].Text = "0";
                        }
                        if (!Convert.IsDBNull(e.Row.Cells[ro].Text))
                        {
                            _total[jo] += Convert.ToDecimal(e.Row.Cells[ro].Text);
                            total = total + Convert.ToDecimal(e.Row.Cells[ro].Text);
                            if (jo == days)
                            {
                                e.Row.Cells[ro + 1].Text = Convert.ToString(total);
                            }
                        }
                        ro += 1;
                        jo += 1;
                    }
                }
            }
}
