Question

I’m trying to implement breadcrumb functionality on a visual studio ASP C# site using the SiteMapPath Control.

The company I work for has inherited the site and we’re primarily PHP developers so forgive the ignorance.

Originally when I dropped in the SiteMapPath from the tool box I got an error message saying there was no web.sitemap file found. I then created one using an application that supposedly does the job for ASP sites.

The error message we get now tells us that your not allowed to have the same URL twice in the xml structure. This seems pretty ridiculous as many pages will have the same links.

Some research has told me to append each of the URLs with a unique virtual useless requeststring in the xml. This also seems a bit ridculous, and a total hack – especially with a site containing potentially hundreds of urls repeated.

Can anyone shed a little light on this, or maybe even a totally different approach??

Thanks so much!

“The error message we get now tells us that your not allowed to have the same URL twice in the xml structure. This seems pretty ridiculous as many pages will have the same links.”

I think there’s a bit of confusion: Pages having the same links is irrelevant – web.sitemap is just an XML map of page locations. The file doesn’t record page cross-linking. But, you can nest things as such if they have identical names:

<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
    <siteMapNode url="/" title="Home">
        <siteMapNode url="/subdir" title="Subdir">
            <siteMapNode url="/subdir/page.aspx" title="Nested Page" />
        </sitemapNode>
        <siteMapNode url="/page.aspx" title="Root Page" />
    </siteMapNode>
</siteMap>
