1.使用者控件
webusercontrol.ascx
<%@ control language="c#" autoeventwireup="true" codefile="webusercontrol.ascx.cs" inherits="webusercontrol" %>
<asp:label id="label1" text="mzwu.com" runat="server" height="20px" width="226px"></asp:label>
<asp:label id="label2" runat="server" text="hello world!" height="20px" width="226px"></asp:label>
webusercontrol.ascx.cs
using system;
using system.data;
using system.configuration;
using system.collections;
using system.web;
using system.web.security;
using system.web.ui;
using system.web.ui.webcontrols;
using system.web.ui.webcontrols.webparts;
using system.web.ui.htmlcontrols;
public partial class webusercontrol : system.web.ui.usercontrol
{
public string message
{
get { return label1.text; }
}
}
2.通路用控件裡面的控件
default.aspx:
<%@ page language="c#" autoeventwireup="true" codefile="default.aspx.cs" inherits="_default" %>
<%@ register src="webusercontrol.ascx" tagname="webusercontrol" tagprefix="mycontrol" %>
<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>通路使用者控件中的控件-mzwu.com</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<mycontrol:webusercontrol id="webusercontrol1" runat="server" />
</div>
</form>
</body>
</html>
default.aspx.cs
public partial class _default : system.web.ui.page
protected void page_load(object sender, eventargs e)
response.write(webusercontrol1.message);//方法一：使用屬性通路
response.write(((label)webusercontrol1.findcontrol("label2")).text);//使用findcontrol方法
