Call this Method on some button click or on new row creation or whatever event you want to

C#

private void GrandTotal()
    {
     float GTotal = 0f;
     for (int i = 0; i < GridView1.Rows.Count; i++)
     {
        String total = (GridView1.Rows[i].FindControl("lblTotal") as Label).Text;
        GTotal += Convert.ToSingle(total);
     }
     txtTotal.text=GTotal.toString();
    }

Hope it will help..
