[转]利用GridView显示主细表并一次编辑明细表所有数据的例子

原文链接：http://dotnet.aspx.cc/article/2cb1c6d7-2b22-4655-8922-2a8a053a66fa/read.aspx

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" %>


利用GridView显示主细表并一次编辑明细表所有数据的例子

td,div,a {font-size:12px}

//function ShowHidden(sid,ev)
{
ev = ev || window.event;
var target = ev.target || ev.srcElement;
var oDiv = document.getElementById("div" + sid);
oDiv.style.display = oDiv.style.display == "none"?"block":"none";
target.innerHTML = oDiv.style.display == "none"?"显示":"隐藏";
}

" type="hidden" />
" value="<%#eval("title") %>" style="width: 100%;border:1px solid gray" />

" value="<%# ((DateTime)Eval("CreateDate")).ToString("yyyy-MM-dd") %>" style="border:1px solid gray"/>
