ASP.NET

<asp:GridView ID="grdCommAppl" Width="100%" runat="Server" AutoGenerateColumns="False"

                                                                              <columns>
                                                                                  <asp:TemplateField HeaderText="SlNo" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left">

                                                                              </columns>

Code:

C#

protected void btnCalculate_Click(object sender, ImageClickEventArgs e)
    {
                decimal totamttopaid = 0;
    for (int i = 0; i < grdCommAppl.Rows.Count; ++i)
    {
       totamttopaid += Convert.ToDecimal((grdCommAppl.Rows[i].Cells[11].ToString()));
    }
    txtTotamt.Text = totamttopaid.ToString();
    }
}

I need to calculate like this

Total Amount to be paid= sum(Amount to Be paid)

Please help me to write logic

Thanks

C#

int ColIndex = // The Column index of "Amount to Be Paid"
decimal totalAmt = 0;
foreach(GridViewRow gr in grdCommAppl.Rows)
{
    decimal thisTotal = 0;
    if (decimal.TryParse(((TextBox)gr.Cells[ColIndex].FindControl("txtAmttobePaid")).Text, out thisTotal))
    {
         totalAmt += thisTotal;
    }
    else
    {
        throw new Exception("Invalid total amount detected. (Non-numeric)");
    }
}
return totalAmt;
