按下按钮并在文本框中显示结果时在Gridview中添加一列

我是的初学者，ASP.NET多年来一直坚持使用此代码。

我一直试图在中添加一列，GridView并在TextBox用户按下按钮时显示结果。

我在下面的行上收到一条错误消息- no exception method "value" accepting the first argument of type

这是完整的C＃代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;
using System.Data.OleDb;
using FinanceSystemVS2013_05;
using System.Web.UI.WebControls.TableCell;

namespace FinanceSystemVS2013_05._02._14
{
    public partial class Sales_Transaction : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
        }
        protected void calInterestBtn_Click(object sender, EventArgs e, GridView g)
        {

            if (g.Columns[15].HeaderText == "interest_amount")
            {
                //if (e.ColumnIndex == 5)
                    calInterestTxt.Text = CellSum().ToString();
            }
        }

        private double CellSum()
        {
            double sum = 0;
            for (int i = 0; i < sTransactionEnquiryDB.Rows.Count; ++i)
            {
                double d = 0;
                Double.TryParse(sTransactionEnquiryDB.Rows[i].Cells[15].Value.ToString(), out d);
                sum += d;
            }
            return sum;
       }
}

尝试使用以下内容，并检查其是否工作正常：

用于添加兴趣的按钮的Aspx代码：

<asp:Button ID="calInterestBtn" runat="server" Text="Calculate Interest" OnClick="calInterestBtn_Click"/>

click事件方法的背后代码：

protected void calInterestBtn_Click(object sender, EventArgs e)
        {
            double sum = 0.0;
            foreach (GridViewRow row in sTransactionEnquiryDB.Rows)
            {
                Double d = Convert.ToDouble(row.Cells[14].Text);
                sum += d;
            }

            calInterestTxt.Text = sum.ToString();
        }
