将数据从内部网格视图传递到主网格视图（gridview 模板中的网格视图）ASP.net C#

Question

我在将数据从内部网格传递到主网格时遇到了一些麻烦，如图所示

我尝试了太多的解决方案，我可以使用 C# 和 Jquery 这是简单的照片结果

现在这是从数据库读取的发票以显示多个数据，如图所示，网格包含另一个网格，正常代码无法访问 gridview2 来获取数据
我想要的只是从gridview2获取“金额”然后计算“sum”然后将其传递给gridview1中的“total”我也使用Jquery它什么都不做这是两个字段的简单代码我想用Jquery求和

 <script type="text/javascript"> $(function () { var fields = document.getElementsByClassName('clstocal'); var sum = 0; for (var i = 0; i < fields.length; ++i) { var item = fields[i]; sum += parseInt(item.innerHTML); } $("#totalprice").text(sum); }); // this code get it from this site </script>

<asp:TextBox ID="amount" CssClass ="clstocal" autopostback="true" runat="server" Enabled="False" Height="24px" Text='<%# Bind("body_total") %>' Width="98px" OnTextChanged="amount_TextChanged"></asp:TextBox>

和

<asp:TextBox ID="totalprice" runat="server" Enabled="False" Height="22px" Width="145px" OnTextChanged="totalprice_TextChanged" autopostback="true"></asp:TextBox>

有一个简单的解决方案，但不是一个好的解决方案是将结果汇总到数据库然后再次读取，但这根本没有效率..

Answer 1

老实说，答案很简单 1. 无法访问网格内的网格 2. 通过 C# 中的普通代码解决，如图所示

    protected void GridHead(object sender, GridViewRowEventArgs e)
    {
        // MAin Grid which is grid number 1 
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            TextBox textboxPrice1 = e.Row.FindControl("totalprice") as TextBox;
            textboxPrice1.Text = i.ToString();
            i = 0; // Global double -> protected double i = 0; // THIS LINE TO STOP COUNTING TO OTHER NEXT INVOICE

        }

    }

    protected void GridBody(object sender, GridViewRowEventArgs e)
    {
        // Inner grid which contain multipe item need to sun then send it to Main grid
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            TextBox lblPrice2 = e.Row.FindControl("amount") as TextBox;
            i += Convert.ToDouble(lblPrice2.Text);
        }
    }

以及处理网格的代码

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Reports._Default" %>
