Hey
you can add footer Template in the your GridView (ItemGv).

C#

<FooterTemplate>
     <asp:Label ID="lblsum" runat="server"></asp:Label>
 </FooterTemplate>

Also handle the RowDataBound() event for it.

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
 if (e.Row.RowType == DataControlRowType.DataRow)
 {
  decimal rTotal = Convert.ToDecimal
              (DataBinder.Eval(e.Row.DataItem, "totaltb"));
  grsum = grdTotal + rTotal ;
 }
 if (e.Row.RowType == DataControlRowType.Footer)
 {
  Label lblsum= (Label)e.Row.FindControl("lblsum");
  lblsum.Text = grsum.ToString("c");
 }
}

Try this:

C#

int sum = 0;
TextBox txt;
foreach(GridViewRow row in ItemGv.Rows)
{
   txt = (TextBox)row.Cells[4].FindControl("totaltb");
   sum += Convert.ToInt32(txt.Text);
}
