什么时候添加了ctl00前缀？ [英] When is the ctl00 prefix added?
问题描述
我有一个简单的asp.net页面，带有一个asp.net链接按钮和asp.net内容标签，它指向一个带有asp.net内容占位符和表单标签的简单asp.net母版页。以下是这两项内容的代码：
Site.Master：
<％@ Master Language =C＃AutoEventWireup =trueCodeBehind =Site.master.csInherits =WebApplication1.SiteMaster％>
< html xmlns =http://www.w3.org/1999/xhtml>
< head>
< title>< / title>
< / head>
< body>
< form runat =server>
< asp：ContentPlaceHolder ID =MainContentrunat =server/>
< / form>
< / body>
< / html>
Default.aspx：
<％@ Page Title =Home PageLanguage =C＃MasterPageFile =〜/ Site.masterAutoEventWireup =true
CodeBehind =Default.aspx.cs Inherits =WebApplication1._Default％>
< asp：Content ID =BodyContentrunat =serverContentPlaceHolderID =MainContent>
< asp：LinkButton ID =LinkButton1runat =server> LinkButton< / asp：LinkButton>
< / asp：Content>
由于某些原因，当我们在一台服务器上运行这个简单的Web应用程序时，链接bhutton的id为MainContent_LinkButton1
，当我们在另一台服务器上运行这个应用程序时，链接按钮得到的id是_ctl0_MainContent_LinkButton1
Doese某人有一个idia为什么我们得到前缀 ctl0 在特定的服务器和另一台服务器上我们没有得到它？
我从 .Net 3.5 迁移到 .Net 4.0 。
我通过在IIS6的 web.config 中添加以下配置来解决这个问题。对于IIS7，请使用 system.webServer 部分：
<系统名.web>
I have a simple asp.net page with an asp.net link button and asp.net content tag which point to a simple asp.net master page with an asp.net content place holder and a form tag. Here is the code of these two items:
Site.Master:
<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site.master.cs" Inherits="WebApplication1.SiteMaster" %>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
</head>
<body>
<form runat="server">
<asp:ContentPlaceHolder ID="MainContent" runat="server"/>
</form>
</body>
</html>
Default.aspx:
<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
<asp:LinkButton ID="LinkButton1" runat="server">LinkButton</asp:LinkButton>
</asp:Content>
For some reason when we run this simple web application on one server the id the link bhutton get is MainContent_LinkButton1 and when we run this application on another server the id the link button get is _ctl0_MainContent_LinkButton1
Doese someone have an idia why we get the prefix ctl0 in a specific server and in another server we don't get it?
I had the same problem when I migrated from .Net 3.5 to .Net 4.0.
I solved it by adding the following configuration in web.config in IIS6. For IIS7, use the system.webServer section:
<system.web>
<pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/>
</system.web>
