I am trying to implement a scheme where navigation is split among 2 controls:  Across the top of the page is a menu control that displays only the top-level sitemap nodes (2 levels, including root), in the form of clickable tabs.  Down the left side of the page is a TreeView which acts as a submenu, whose DataSource changes to display the children of the selected top menu item.  Similar to what this fellow describes here: http://forums.asp.net/thread/931021.aspx.  However, I have implemented a custom SiteMapProvider.

I also don't want to navigate to a new page when the user clicks on one of the top menu tabs- I just want to postback so I can update my TreeView submenu, leaving alone whatever may be in the content area.  Therefore, my top-level folders do not have NavigateURLs.

My problem is that when I declare my top Menu as  

StaticDisplayLevels="2" MaximumDynamicDisplayLevels="0"

then my top level folders appear as non-clickable text, preventing me from selecting them.

What am I missing?  Do I need to provide a NavigateURL for the top-level folders?  I tried making them "#", but that's not unique...

Thanks for any help you can provide!

Carl

Can anyone help me on this?

Thanks!

hi!

just modify sitemap file:

<siteMapNode url="~/Intro.aspx" title="Main1"  description="">
    <siteMapNode url="~/Default.aspx?page=1" title="Main2" description="" />
    <siteMapNode url="~/Default.aspx?page=2" title="Main2" description="" />
    <siteMapNode url="~/Default.aspx?page=3" title="Main2" description="" />
    <siteMapNode url="~/Default.aspx?page=4" title="Main2" description="" />
    <siteMapNode url="~/Default.aspx?page=5" title="Main2" description="" />
</siteMapNode>

Hmm, well I don't have a sitemap file- I'm using a custom SiteMapProvider that gets a feed from a web service.

I worked around the issue by explicitly setting each of the menu items to "selectable" (Items(0) is the root):

For Each temp As MenuItem In topMenu.Items(0).ChildItems
    temp.Selectable = True
Next

But I'd sure like to know the real answer...

Thanks though,

Carl

hi!

all you have to do is set NavigateUrl of each item to the same page.

But I don't want to navigate anywhere, I just want to do a postback.  I want to leave untouched whatever page contents is being currently displayed.

Am I missing something?

Thanks, Carl

hi!

ok, this should work:

add TreeNodeDataBound event handler:

protected void TreeView1_TreeNodeDataBound(object sender, TreeNodeEventArgs e)
    {       
        e.Node.NavigateUrl = ClientScript.GetPostBackClientHyperlink( TreeView1,e.Node.Value,false );

    }

then in Page load event handler:
    if ( IsPostBack )
        {
            if ( Request[ "__EVENTTARGET" ].ToString() == "TreeView1" )
            {
                //what node?
                string val = Request[ "__EVENTARGUMENT" ].ToString();
            }
        }

also modify <%@Page> and set EnableEventValidation to false.
