<!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>MasterPage</title>

<asp:ContentPlaceHolder ID="head" runat="server">

</asp:ContentPlaceHolder>

</head>

<body>

<form id="form1" runat="server">

<div>

<br />

<br />

<asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">

</asp:ContentPlaceHolder>

</div>

</form>

</body>

</html>

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage/MasterPage.master" AutoEventWireup="true"

CodeFile="SubPage.aspx.cs" Inherits="MasterPage_SubPage" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">

<asp:Label ID="Sub_Label" runat="server" Text="Label"></asp:Label>

<br />

<br />

<asp:Button ID="Button1" runat="server" Text="子页1访问母页1"

onclick="Button1_Click" />

<asp:Button ID="Button2" runat="server" Text="子页1注销母页1"

onclick="Button2_Click" />

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

public partial class MasterPage_SubPage : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

Sub_Label.Text = "子页Label";

}

// 访问母版页，并登陆

protected void Button1_Click(object sender, EventArgs e)

{

Label mLabel = (Label)Master.FindControl("Master_Label");

mLabel.Text = "子页 - 访问母版页";

}

// 访问母版页，并注销

protected void Button2_Click(object sender, EventArgs e)

{

Label mLabel = (Label)

Master.FindControl

("Master_Label");

mLabel.Text = "母版页(Label)";
