hi. What is this error when I use SiteMapPath . when I click One link in my webSite , this error appeared in a page . of course when I upload my website,I See this error :

The page cannot be found The page you are looking for might have been removed, had its name changed, or is temporarily unavailable.

Based on the error, it appears that the URLs in your SiteMap are not relative. For example, let's say you have a subdirectory called "Example" and a page called "test.aspx" located in that "Example" directory. This entry would produce a 404 error (page not found).

<siteMapNode url="Test.aspx" title="Test Page" />

This would be the correct siteMapNode entry:

<siteMapNode url="~/Example/Test.aspx" title="Test Page" />
