Great example at http://www.telerik.com/community/forums/thread/b311D-eaged.aspx
for what I want to do. That is, highlight the root parent of the page I am on. Problem with the example is the following code that is put in the page load event to call the showpath method:
Dim clickedItem As RadMenuItem = Menu1.FindItemByUrl(Request.Url.PathAndQuery)
The Request.Url.PathAndQuery comes back only as default.aspx with the querystring. Assume this is due to URL rewriting for friendly urls. So, how do I get the friendly url for the page we are on to compare with the menu item data for the same page?
