I want to highlight the parent menu item on selecting the child menu item. I have written the script written in the examples, but the FindItemByUrl returns empty don't know why.
Here is the script.
   Dim currentItem As RadMenuItem = RadMenu1.FindItemByUrl(Request.Url.PathAndQuery)
        If currentItem IsNot Nothing Then
            'Select the current item and his parents
            currentItem.HighlightPath()
         
        Else
            RadMenu1.Items(0).HighlightPath()
        End If
