Master pages are a great addition to the ASP.NET 2.0 feature set. Master pages help us build consistent and maintainable user interfaces. Master pages, however, are not without their quirks. Sometimes master page behavior is surprising, and indeed the very name master page can be a bit misleading. In this article, we are going to examine some of the common problems developers run into when using master pages, and demonstrate some practical advice for making effective use of master pages. For an introduction to master pages, see "Master Pages In ASP.NET 2.0".
To make use of master pages, we first need to understand how master pages work. Many of the tips and traps covered later in this article revolve around understanding the magic behind master pages. Let’s dig into these implementation details first.
For Internal Use Only
When a web request arrives for an ASP.NET web form using a master page, the content page (.aspx) and master page (.master) merge their content together to produce a single page. Let’s say we are using the following, simple master page.
<%@ Master Language="VB" %>
Untitled Page
The master page contains some common elements, like a head tag. The most important server-side controls are the form tag (form1) and the ContentPlaceHolder (ContentPlaceHolder1). Let’s also write a simple web form to use our master page.
<%@ Page Language="C#" MasterPageFile="~/Master1.master"
AutoEventWireup="true" Title="Untitled Page" %>
ContentPlaceHolderID="ContentPlaceHolder1" >
