This is part three of a three part
article that demonstrates how to build an ASP.NET
navigation system. In part one, web pages were added
to a web site and then referenced in a ASP.NET 2.0
SiteMap file. In part two an ASP.NET 2.0 Menu
control was tied to the SiteMap file created in part
one. In part three an ASP.NET SiteMapPath (bread
crumbs menu) is tied to the SiteMap created in part
one and the Menu added in part two.

Clean Up the Master Page
The master page used in parts 1
and 2 was getting cluttered so I clean it up. Here
are the steps I took:
1. Removed the Read Me and
GetDotNetCode links below the banner header.
2. Merged the two cells below the
banner header.
3. Removed the row above the
banner header that contained the words: 'Bread
Crumbs Menu (Will be added in Part Three)'
Add an ASP.NET 2.0 SiteMapPath
Control to the Master Page
An ASP.NET 2.0 SiteMapPath control
was drug from the Toolbox to the row under the
banner header.
Because a site map with the name
Web.sitemap was already present in the web sites
root directory, the new control was automatically
wired to it. (The site map was added in part one of
this article.)
Test the Site Map
Run the application. Select any
page from the application, from the left menu. As
you do, the SiteMapPath control will display a
'bread crumbs' menu that shows the path to the page
you select.
About the ASP.NET SiteMapPath
Class
The SiteMapPath control is a site
navigation control that reflects data provided by
the SiteMap object. The SiteMapPath class displays a
set of text or image hyperlinks that enable users to
more easily navigate a Web site, while taking a
minimal amount of page space.
The SiteMapPath control provides a
space-saving way to easily navigate a site and
serves as a point of reference for where the
currently displayed page is within a site. This type
of control is commonly called a breadcrumb, or
eyebrow, because it displays a hierarchical path of
hyperlinked page names that provides an escape up
the hierarchy of pages from the current location.
SiteMapDataSource.
