    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.

    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!
