Introduction IntroductionOne common characteristic of user-friendly websites is that they have a consistent, site-wide page layout and navigation scheme. ASP.NET 2.0 introduces two new features that greatly simplify implementing both a site-wide page layout and navigation scheme: master pages and site navigation. Master pages allow for developers to create a site-wide template with designated editable regions. This template can then be applied to ASP.NET pages in the site. Such ASP.NET pages need only provide content for the master page's specified editable regions – all other markup in the master page is identical across all ASP.NET pages that use the master page. This model allows developers to define and centralize a site-wide page layout, thereby making it easier to create a consistent look and feel across all pages that can easily be updated. The site navigation system provides both a mechanism for page developers to define a site map and an API for that site map to be programmatically queried. The new navigation Web controls – the Menu, TreeView, and SiteMapPath – make it easy to render all or part of the site map in a common navigation user interface element. We'll be using the default site navigation provider, meaning that our site map will be defined in an XML-formatted file. To illustrate these concepts and make our tutorials website more usable, let's spend this lesson defining a site-wide page layout, implementing a site map, and adding the navigation UI. By the end of this tutorial we'll have a polished website design for building our tutorial web pages.
