前几天写了一个利用GridView显示主细表的例子，有网友询问如何一次编辑明细表数据所有数据？其实，如果对ASP.NET或者HTML比较熟悉的话，这种批量编辑数据的功能很容易实现。下面的例子使用隐藏表单域记录数据的标识id，对每个输入框的名字附加id信息，这样的话，数据对应起来比较简单。

例子中使用的数据库来自《ASP.NET 2.0 应用开发技术》一书。换成其它数据库也类似，看懂代码，怎么换就无妨了。

ASPx：

<%@ Page Language="C#" ValidateRequest="false" AutoEventWireup="true" EnableViewState="true"

CodeFile="Default2.aspx.cs" Inherits="Default2" %>
