这是子母版内容

我将基于此嵌套母版页创建一个页面：

<%@ 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>

<%@ 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>

我想点击

按钮1

获取主页面文本

如何执行此操作？

在PageMasterPageNested.aspx中：

TextBox txtBox = this.Master.Master.FindControl("txtMasterPageMaster") as TextBox;

应该有用。试试看。希望有帮助。

这在任何情况下都有效。特别是如果你不知道或不关心嵌套了多少母版页。希望有帮助：）
