I had been using web.sitemap with Menu control for navigation purpose. The following is my web.sitemap.

<siteMapNode url="~/index.aspx" title="Home"  description="Home">
     <siteMapNode url="" title="City" description="City">
         <siteMapNode url="~/city_list.aspx" title="City List"  description="City List" />
         <siteMapNode url="~/city_entry.aspx" title="City Entry"  description="City Entry" />
     </siteMapNode>
     <siteMapNode url="" title="State" description="State">
         <siteMapNode url="~/state_list.aspx" title="State List"  description="State List" />
         <siteMapNode url="~/state_entry.aspx" title="State Entry"  description="State Entry" />
     </siteMapNode>
</siteMapNode>


I bind it to SiteMapDatasource and thus bind to Menu control. Is there any way to highlight the root node (eg. City, State) instead of highlighting its child node (eg. City List, City Entry, State List, State entry)
 when we are browsing the child node on web.

I have heard that in the MenuItemDataBound event, if you determine that the current Node is the selected one, you can set the parent to selected as well and it will apply the selected node style.  Ironically this would be in someways a bug since multiple selected nodes would exist but since it's not filed, it likely won't get fixed.  In general a "parent selected style" is something certainly on the plate for enhancements to the Menu control in the future.

Surely. Here's what I do to always select the 2nd level node regardless of how deep the user is in the SiteMap (or Home, since I flatten the first two levels for my menu.)

    Protected Sub mnuHead_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles mnuHead.DataBound
        If Not SiteMap.CurrentNode Is Nothing Then
            Dim node As SiteMapNode
            Dim prev As SiteMapNode 'ultimately the "level 2" root of whatever the current node is
            node = SiteMap.CurrentNode
            prev = SiteMap.CurrentNode
            While Not node.ParentNode Is Nothing
                prev = node
                node = node.ParentNode
            End While
            Dim ParentMenu As MenuItem
            Dim ChildMenu As MenuItem

            For Each ParentMenu In mnuHead.Items
                ' only one ParentMenu for me.. home
                If ParentMenu.NavigateUrl = prev.Url Then
                    Exit For
                End If
                ' this is the level i want selected
                For Each ChildMenu In ParentMenu.ChildItems
                    If ChildMenu.NavigateUrl = prev.Url Then
                        ChildMenu.Selected = True
                        Exit For
                    End If
                Next
            Next
        End If
    End Sub

in he item menu data bind....
you could do something like
if (e.item node == sitemap.currentnode.parent)
          item.text = "<span class=\"selectedItemCSS\">" + text + "</span>";

check the syntax online at http://www.msdn.com or scott guthries blog for sure, but more orless that is what you will want to do.

Hello there,

I am trying to implement the same thing. But couldn't find answer to this and come across to your post.

If you've implemented this or sorted this problem, can you please tell me that how did u do it. I really want to solve this. If there's any sample code or link, then can you plz provide me that.

I would welcome to hearing from you.

Many thnx,

vishal.

Vishal had posted one question for me which is about how to select the 3rd level node instead of 2nd level node. Since this question is same for my post, I had modified the solution provided by ryanr to adapt this situation. Vishal's menu view is as follow and he wants to highlight 3rd level node (Course List) instead of 2nd level node when he browses to 4th level node (Course Details).

Home

   Courses

      Course List

         Course Details

The solution is shown below:

    Protected Sub Menu1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles Menu1.DataBound
        If Not SiteMap.CurrentNode Is Nothing Then
            Dim node As SiteMapNode
            Dim prev As SiteMapNode
            node = SiteMap.CurrentNode
            prev = SiteMap.CurrentNode

            While Not node.ParentNode.ParentNode Is Nothing
                prev = node
                node = node.ParentNode
            End While

            Dim ParentMenu As MenuItem
            Dim ChildMenu As MenuItem
            Dim SubChildMenu As MenuItem

            For Each ParentMenu In Menu1.Items
                ' only one ParentMenu for me.. home
                If ParentMenu.NavigateUrl = prev.Url Then
                    Exit For
                End If
                ' the second level is my choice too
                For Each ChildMenu In ParentMenu.ChildItems
                    If ChildMenu.NavigateUrl = prev.Url Then
                        Exit For
                    End If

                    ' this is the 3rd level to be selected
                    For Each SubChildMenu In ChildMenu.ChildItems
                        If SubChildMenu.NavigateUrl = prev.Url Then
                            SubChildMenu.Selected = True
                            Exit For
                        End If
                    Next
                Next
            Next
        End If
    End Sub
