Hi,

they certainly have not discontinued it! I think you might be overlooking the fact that nested masterpages are just masterpagesthat inherit from other masterpages.

So just use the Master Page template in (web > c#)

I tried that while watching the vides tutorial it acted no differnt than than a regular aspx page other than the nestedmaster page wont display  

any content untill I add a content page to the nestedmaster then any content I put in the nestedmaster page displays if I try to put any content

in the aspx page I added I get an error

this is  the nestedmaster

<%@ Master Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="MasterPage2.master.cs" Inherits="MasterPage2" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<div style="height: 136px"></div>

</asp:Content>

and this is the content page

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage2.master" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>

<%-- Add content controls here --%>

when I try to put anything inthe content page I get this error

System.Web.HttpException: Content controls have to be top-level controls in a content page or a nested master page that references a master page<?xml:namespace prefix = asp /><asp:Content class=st id="

 

</asp:Content>

Hello There,

you are almost there, 2 changes.

first in you child Master Page add a <asp:ContentPlaceHolder> inside the <asp:content id="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

so your child MasterPage will look like this now

<%@ Master Language="C#" AutoEventWireup="true" MasterPageFile="~/Main.master" CodeFile="Child.master.cs" Inherits="Child" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">

<h4>this is child master using contentplaceholder id = head</h4>

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

<h4>Welcome to Child Master Page. I am using Contentplaceholder id = ContentPlaceHolder1</h4>

<asp:ContentPlaceHolder ID="cpChild" runat="server">

</asp:ContentPlaceHolder>

</asp:Content>

now in your aspx.page

<%@ Page Language="C#" MasterPageFile="~/Child.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" Title="Untitled Page" %>

<%-- Add content controls here --%>

<asp:content id="cMain" runat="server" contentplaceholderid="cpChild" >

<div id="cats" runat="server">

<asp:Image ID="Image1" runat="server" ImageUrl="~/images/curleft.jpg" /></div>

 

</asp:content>

now it will run.

Hope this helps !!

Thanks

 just a note on novicehere's post: you don't have to change the placeholder id in your nested masterpage. You can just do:

<asp:Content id="content2" runat="server" ContentPlaceHolderID="ContentPlaceholder1">
  <asp:ContentPlaceholder runat="server" id="ContentPlaceholder1" />
</asp:Content>

this way, if you ever decide to remove the nested masterpage, your contentpages won't break cause they'll find the placeholder in the root master.
