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.

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="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>
