I am afraid that the issue is not reproducible on my side with the latest version of Telerik UI for ASP.NET AJAX. As far as the demo is concerned, all nodes in the demo have NavigateUrl set to #, thus it is expected that no navigation occurs, when a RadSiteMap node is tapped inside a RadMenu template. I just substituted the # with a real URL and navigation occurs as expected.
If you are not using the latest version, probably your version was released before the following issue
has been fixed. I would suggest you to test with our latest version on your end.
