我有 2 个嵌套的母版页。这是主母版页代码，例如：
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPageMaster.master.cs" Inherits="MasterPageMaster" %>
<!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></title>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="txtMasterPageMaster" ClientIDMode="Static" runat="server"></asp:TextBox>
<div style="background-color:Aqua;height:40px;">
Some Text
</div>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
和嵌套母版页：
<%@ Master Language="C#" MasterPageFile="~/MasterPageMaster.master" AutoEventWireup="true"
CodeFile="MasterPageNested.master.cs" Inherits="MasterPageNested" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
<asp:Panel runat="server" ID="panelMain" BackColor="lightyellow">
<h2>
Child master</h2>
<asp:Panel runat="server" ID="panel1" BackColor="lightblue">
<p>
This is child master content.</p>
<asp:ContentPlaceHolder ID="ChildContent1" runat="server" />
</asp:Panel>
<asp:Panel runat="server" ID="panel2" BackColor="pink">
<p>
This is child master content.</p>
<asp:ContentPlaceHolder ID="ChildContent2" runat="server" />
</asp:Panel>
<br />
</asp:Panel>
</asp:Content>
我基于此嵌套母版页创建一个页面：
<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPageNested.master" AutoEventWireup="true" CodeFile="PageMasterPageNested.aspx.cs" Inherits="PageMasterPageNested" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ChildContent1" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ChildContent2" Runat="Server">
<asp:Button ID="Button1" runat="server" Text="Button" Height="66px"
onclick="Button1_Click" Width="196px" />
</asp:Content>
我想要点击Button1获取主母版页的文本。
我怎样才能做到这一点？
在 PageMasterPageNested.aspx 中：
TextBox txtBox = this.Master.Master.FindControl("txtMasterPageMaster") as TextBox;
应该管用。试一试。希望能帮助到你。
