<asp:TemplateField HeaderText="Amount" SortExpression="Amount">
<ItemTemplate>
<asp:Literal ID="AmountLiteral" runat="server" />
</ItemTemplate>
<FooterTemplate>
<asp:Literal ID="AmountTotal" runat="server" />
</FooterTemplate>
</asp:TemplateField>

In your code behind, you have a private variable on top as global variable.

private decimal total = 0;

In your onRowDataBound Method, each row, I get the amount and add it to total, when I reached the footer, I simply set to the literal of the total value.

protected void InvoicesGridView_DataBound(object sender, GridViewRowEventArgs e)
{
Invoices_Ext invoice = (Invoices_Ext)e.Row.DataItem;
if (e.Row.RowType == DataControlRowType.DataRow)
{
Literal AmountLiteral = (Literal)e.Row.FindControl("AmountLiteral");
AmountLiteral.Text = String.Format("{0:C2}", invoice.InvoiceAmount);
total += invoice.InvoiceAmount.Value;
}
if (e.Row.RowType == DataControlRowType.Footer)
{
Literal AmountTotal = (Literal)e.Row.FindControl("AmountTotal");
AmountTotal.Text = String.Format("{0:C2}", total);
}
}

Thanks

Add the footer Template:
 
<asp:TemplateField HeaderText="Id">
  <ItemTemplate>
  <asp:Label ID="lblprice" runat="Server" Text='<%# Eval("price") %>' />
  </ItemTemplate>
  <FooterTemplate>
  <asp:Label ID="lbltotal" runat="server" />
  </FooterTemplate>
</asp:TemplateField>
 
Implement the RowDataBound
 
decimal totalPrice = 0M;
int totalItems = 0;
 
 
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
  {
  if (e.Row.RowType == DataControlRowType.DataRow)
  {
    Label lblPrice = (Label)e.Row.FindControl("lblprice");
    decimal price = Decimal.Parse(lblPrice.Text);
    totalPrice += price;
    totalItems += 1;
  }
  if (e.Row.RowType == DataControlRowType.Footer)
  {
    Label lblTotalPrice = (Label)e.Row.FindControl("lbltotal");  
    lblTotalPrice.Text = totalPrice.ToString();  
  }
  }

hi,

Instated of using grid view row property retrive no of rows from the data set directly because row property changes with the paging

     foreach (DataRow row in ds1.Tables[0].Rows)
                        {
                            totCal += Convert.ToDouble(row["salary"]);
                        }
                        lblsal.Text = " " + totCal;

Hope will works!!!!!!!!!

Regards,
