This show is a video demo of creating a nested master page in Visual Studio 2008.
The source code for the parent master page is:
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPageParentSimple.master.cs" Inherits="MasterPageParentSimple" %>
<!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>Untitled Page</title>
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<div>
Simple Parent Master Page.<br />
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
The source code for the example child master page is:
<%@ Master Language="C#" MasterPageFile="~/MasterPageParentSimple.master" AutoEventWireup="false" CodeFile="MasterPageChildSimple.master.cs" Inherits="MasterPageChildSimple" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
Simple Child Master Page<br />
The location of the ContentPlaceHolder was the one hangup I had.<br />
<asp:ContentPlaceHolder ID="Content3" runat="server">
</asp:ContentPlaceHolder>
</asp:Content>
The source code for the example simple out page is:
<%@ Page Language="C#" MasterPageFile="~/MasterPageChildSimple.master" AutoEventWireup="true" CodeFile="DefaultSimpleMasterPageExample.aspx.cs" Inherits="DefaultSimpleMasterPageExample" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="Content3" Runat="Server">
this is some basic content. this is more content.
</asp:Content>
Here is some exact output (not a perfect match, but close).
