Hi all,

I'm attempting to set the style of a root menuitem to it's focussed state when an item in its submenu has been selected. I'm doing this in a master page, code as follows:

Private Sub sitemenu_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadMenuEventArgs) Handles sitemenu.ItemCreated
        Dim item As RadMenuItem = sitemenu.FindItemByUrl(Request.Url.PathAndQuery)
        If item IsNot Nothing Then
            item.CssClass = "focused"
        End If
 
    End Sub


This works great, and the root items show the focussed state when clicking between them. However when i click on a child item, the root menu item does not have the focused class added to it. Any pointers?

Hello Big Daftie,

Please, see the Show Path And BreadCrumb demo. Basically,  you need to call the HighlightPath() method of the current item.


All the best,

Hi there Peter,

thanks for you reply. I actually sorted this myself - I was using loadcontentfromfile(), which did not databind the xml so could not use the itemdatabound() handler.

I've now moved the code to itemdatabound, and modified it to the following (in the unlikely event it's of use to anyone else):

Dim item As RadMenuItem = sitemenu.FindItemByUrl(Request.Url.PathAndQuery)
If item IsNot Nothing Then
    If item.Level > 0 Then 'menu will only ever be one level deep
        Dim rootitem As RadMenuItem = item.Parent
        rootitem.CssClass = "focused"
    End If
    item.CssClass = "focused"
End If

This seems to work fine - however I'm looking at your breadcrumb demo just now :)

Many thanks!
