Notice the simipler structure of the content page

satya - Tuesday, May 22, 2007 10:48:24 PM

contentplaceholder and content tags

The "content" goes into the "contentplaceholder"

The "contentplaceholderid" of the "content" ties with the "id" of the contentplaceholder tag

you can treat a content page as the child of the master page

satya - Tuesday, May 22, 2007 10:49:53 PM

a child carries the content tag and the master carries the contentplaceholder

masterpages can be nested


<%@ Master Language="C#" 
     MasterPageFile="~/masterpages/SatyaMasterPage.master"
    AutoEventWireup="true" 
    CodeFile="SatyaPageMenuMasterPage.master.cs" 
    Inherits="masterpages_SatyaPageMenuMasterPage" %>

<asp:Content ID="Content1" ContentPlaceHolderID="aspireContent" runat="server">
<table id="contentTableId" width="100%">
<tr>
<td id="contentMainCellId"  width="80%">
<asp:ContentPlaceHolder id="PageContentId" runat="server">
