Calculating Grandtotal in Footer Template of Gridview with Header Template

Hi,

I have a Gridview where I used header templates. Now I want to calculate Grand total in Footer Template. The code is below:-

C#

protected void gvDetails_RowDataBound(object sender, GridViewRowEventArgs e)
    {

C#

if (e.Row.RowType == DataControlRowType.DataRow)
        {
            servchg  += Convert.ToDouble(DataBinder.Eval(e.Row.DataItem, "servicechg"));
        }
        if (e.Row.RowType == DataControlRowType.Footer)
        {
            Label lblservchgamount = (Label)e.Row.FindControl("lblservchg");
            lblservchgamount.Text = servchg.ToString();
        }

}

Now the problem is that I am getting blank Grandtotal column. When debugged I found out that condition "e.Row.RowType == DataControlRowType.DataRow" is bypassed.

Not found any example of a Gridview with both Header and Footer Template in Google .

Please post some, if anybody knows.

Thanks...

ASP.NET

//////it is in aspx page

 <asp:gridview id="gvDetails" runat="server" autogeneratecolumns="False" showfooter="true" datakeynames="id" onrowdatabound="gvDetails_RowDataBound"  />
 
<columns>
<asp:templatefield itemstyle-horizontalalign="Center" footerstyle-horizontalalign="Center" xmlns:asp="#unknown">
                                <HeaderTemplate>
                                    Service Charge</HeaderTemplate>
                                <HeaderStyle  Width="15%" />
                                
                                <itemtemplate>
                                    <asp:label id="lblServChrgRows" runat="server" Text='<%#Eval("servicechg") %>'/>
                                </itemtemplate>

                                <footertemplate>
                                    <div style="text-align:right; padding-removed20px;line-height:18px;">
                                    <asp:label id="lblservchg" runat="server"  />                                      </div></footertemplate></asp:templatefield></columns>
 </asp:GridView>

it is apsx.cs side code

C#

 decimal servchg = 0;
protected void gvDetails_RowDataBound(object sender, GridViewRowEventArgs e)
    {
     if (e.Row.RowType == DataControlRowType.DataRow)
        {  Label lblServChrgRows= (Label)e.Row.FindControl("lblServChrgRows");
                 if (!string.IsNullOrEmpty(lblServChrgRows.text))
                 { 
                servchg += Convert.ToDecimal(lblServChrgRows.text);
                }

            
        }
       
        if (e.Row.RowType == DataControlRowType.Footer)
        { 
            Label lblservchgamount = (Label)e.Row.FindControl("lblservchg");
            lblservchgamount.Text = servchg.ToString();
        }
    }
