I am going to go through a simplified version of the computer sale example. Here is the Master page source.
MasterPage.master
************************************
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="MasterPage" %>
<!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></title>
<link href="StyleSheet.css" rel="stylesheet" type="text/css" />
<asp:ContentPlaceHolder id="head" runat="server">
</asp:ContentPlaceHolder>
</head>
<body>
<form id="form1" runat="server">
<h1>Master Computer Sales</h1>
<p><a href="Default.aspx">Home</a>|<a href="Default2.aspx">Order form</a></p>
<div>
<asp:ContentPlaceHolder id="ContentPlaceHolder1" runat="server">
</asp:ContentPlaceHolder>
</div>
</form>
</body>
</html>
*************************************************
Anything you put on the master page will show on the other pages. On the master page, you never put anything in the contentPlaceHolder. Note the simple menu.
Here is the Stylesheet used with the master page. It is very simple. It is just intended to give the idea of how you would use a style sheet with the Master page.
Stylesheet.css
*****************************************
body
{
font-family:Verdana;
}
h1
{
background-color:Navy;
color:White;
font-weight:bold;
text-align:center;
}
h2
{
color:Navy;
}
*******************************************
To add other pages you need to have the focus on the Master page. That means it must be in the text editor window. Go to Website on the Menu and choose "Add Content Page".
Here is the Default.aspx content page. It contains the overview. It is also the page that will show up when the site is launched.
Default.aspx
*****************************************
<%@ Page Title="Overview" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<h2>Overview</h2>
<p>Master computer is the main purveyor of laptops in the world.</p>
</asp:Content>
******************************************************
Note that the content must be between the contentPlaceHolder tags. The first place holder section is for header elements like scripts or alternate style sheets. The title is specified in the page header.
Here is the Default2.aspx source. It contains a simplified version of the order form.
Default2.aspx
*****************************************
<%@ Page Title="Order" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<asp:SiteMapPath ID="SiteMapPath1" runat="server">
</asp:SiteMapPath>
<p>Choose your computer</p>
<asp:DropDownList ID="DropDownList1" runat="server">
<asp:ListItem Value="400">14 inch</asp:ListItem>
<asp:ListItem Value="500">15 inch</asp:ListItem>
<asp:ListItem Value="600">17 inch</asp:ListItem>
</asp:DropDownList>
<p>Pick hard disk size</p>
<asp:RadioButtonList ID="RadioButtonList1" runat="server">

Here is the code behind for the form page.
