Examples

This section contains three code examples. The first code example demonstrates how to create a nested master page. The second code example demonstrates how to reference the master page that was created in the first code example. The third code example demonstrates how to use a content page to reference the master page that was created in the second code example.

The following code example demonstrates how to create a nested master page and represents the parent master page named ParentMasterPage_1.

<%@ Master Language="C#" %>  

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">  

<html >  
<head runat="server">  
    <title>Nested Master Page Example</title>  
</head>  
<body>  
    <form id="form1" runat="server">  
    <h1>This is content in the parent master page.</h1>  
    <div>  
        <asp:contentplaceholder id="ContentPlaceHolder1" runat="server">  
        </asp:contentplaceholder>  
    </div>  
    </form>  
</body>  
</html>  

<%@ Master Language="VB" %>  

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">  

<html >  
<head runat="server">  
    <title>Nested Master Page Example</title>  
</head>  
<body>  
    <form id="form1" runat="server">  
    <h1>This is content in the parent master page.</h1>  
    <div>  
        <asp:contentplaceholder id="ContentPlaceHolder1" runat="server">  
        </asp:contentplaceholder>  
    </div>  
    </form>  
</body>  
</html>

The following code example demonstrates how to use a nested master page named ChildMasterPage_1 that references the master page that was created in the preceding code example.

<%@ Master Language="C#" MasterPageFile="~/ParentMasterPage_1cs.master" %>  

<asp:Content Runat="Server" ContentPlaceHolderID="ContentPlaceHolder1">  
    <h2>This is the content of a nested Master Page.</h2>  
    <div>  
        <asp:contentplaceholder id="ContentPlaceHolder2" runat="server">  
        </asp:contentplaceholder>  
    </div>  
</asp:Content>  

<%@ Master Language="VB" MasterPageFile="~/ParentMasterPage_1vb.master" %>  

<asp:Content Runat="Server" ContentPlaceHolderID="ContentPlaceHolder1">  
    <h2>This is the content of a nested Master Page.</h2>  
    <div>  
        <asp:contentplaceholder id="ContentPlaceHolder2" runat="server">  
        </asp:contentplaceholder>  
    </div>  
</asp:Content>

The following code example demonstrates how to use a content page named ContentPage that references the ChildMasterPage_1 that was created in the preceding code example.

<%@ Page Language="C#" MasterPageFile="~/ChildMasterPage_1cs.master" Title="Untitled Page"%>  

<asp:content runat="server" contentplaceholderid="ContentPlaceHolder2">  
This is the content of a Content control.  
</asp:content>  

<%@ Page Language="VB" MasterPageFile="~/ChildMasterPage_1vb.master" Title="Untitled Page"%>  

<asp:content runat="server" contentplaceholderid="ContentPlaceHolder2">  
This is the content of a Content control.  
</asp:content>

Remarks
