Step 6: Adding a “Breadcrumb” navigation control to the page

The last touch I want to add to my site is support for a “bread-crumb” UI paradigm near the top of the page that will help users easily figure out where they currently are within the application.  The good news is that this is super easy with ASP.NET 2.0 and the Site Navigation system.

All I need to-do is add the new <asp:SiteMapPath> control to my “header” <div>:

Listing 10

<div id="header">
    <span class="title">Northwind Data Tutorials</span>
    <span class="breadcrumb">
        <asp:SiteMapPath ID="Breadcrumb"  runat="server"></asp:SiteMapPath>
    </span>
</div>

This will then output the site hierarchy of the current node relative to the root node of the site map.  For example, if I was on “Sample1” within the “Basic Data Samples” section of the site, the above control would automatically output this:

Figure 11

If I click on the “Basic Data Samples” hyperlink (which is automatically generated by the breadcrumb – or I could just use the menu link), it would adjust to:

Figure 12

No code is required.

Scott -

Many thanks, this is exactly what I was looking for with the second level repeater nav structure. It would be nice if "the soft" would make their examples half this good!

Scott Gives a great example of converting a sitemap datasource to a bulleted list in this article. However, a code substitution he provided for use in C# does not work. In Visual Studio 2005, I am given the error message, 'System.Web.SiteMapNode.ChildNodes' is a 'property' but is used like a 'method'. Is there a better way to do this?
