            {
               // here you are finding a Label which is not defined in footer template.

                Label lblTotalhours = (Label)e.Row.FindControl("lblTotalhours");
                lblTotalhours.Text = total.ToString();
            }
        }

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
  {
      float grand_total=0;
          if (e.Row.RowType == DataControlRowType.DataRow)
