Web.sitemap - hiding default.aspx but still expanding tree view and breadcrumbs navigation

I have a sitemap, a tree view and a bread crumb control.  In my sitemap I have URLs with the default document suffixed, that is

<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0">
  <siteMapNode url="~/default.aspx" title="Home" description="">

    <siteMapNode title="One" url="~/One/default.aspx">
      <siteMapNode title="Two" url="~/Two/default.aspx">
        ...
etc



The tree view allows me to navigate to these URLs correctly.  However, the tree view is too stupid to understand that / really means /default.asppx, and therefore if I remove the "default.aspx" the treeview does not expand correctly.

What I want is to have the links in my tree view not contain the default.aspx suffix, yet to have the treeview and the breadcrumb expand correctly and show the user where they currently are.


If I change my sitemap to remove the default documents, ie to be this:
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0">
  <siteMapNode url="~/" title="Home" description="">

    <siteMapNode title="One" url="~/One/">
      <siteMapNode title="Two" url="~/Two/">
        ...

then the tree view does not expand the node correctly and the breadcrumb shows nothing.  The treeview expands itsself correctly accordingt o my code, but it refused to recognise that it's at the correct node.  Therefore the current node is not bold and, moreover, the breadscrumb always shows nothing.

Here is my code:



<asp:SiteMapDataSource ID="SiteMapDataSource3" runat="server"  />
       
....
 <asp:TreeView OnTreeNodeDataBound="treeMainMenu_TreeNodeDataBound" ID="TV"
                             SelectedNodeStyle-Font-Bold=true  ExpandImageToolTip="{0}"
                            runat="server" DataSourceID="SiteMapDataSource3"
                            PopulateNodesFromClient="False" ExpandDepth="1" EnableViewState="False"
                                LineImagesFolder="~/i/L/" ShowLines="True"  SkipLinkText="">
                            <ParentNodeStyle ChildNodesPadding="0px"  
                            HorizontalPadding="1px"  />
                            <LeafNodeStyle  VerticalPadding="0px"   HorizontalPadding="1px"    />
                           
                        </asp:TreeView>

....




  protected void  treeMainMenu_TreeNodeDataBound
           ( object  sender ,  System.Web.UI.WebControls.TreeNodeEventArgs e)
        {

            if (
                    (Request.Path.ToLower() == e.Node.NavigateUrl.ToLower())
                     ||
                     (
                        e.Node.NavigateUrl.ToLower().EndsWith("/")
                        &&
                        Request.Path.ToLower() == e.Node.NavigateUrl.ToLower() + "default.aspx"                        
                     )
                )  
            {
                e.Node.ExpandAll();
                e.Node.Parent.ExpandAll();
                // These two lines will prevent self-referencing links to the current URL
                e.Node.SelectAction = TreeNodeSelectAction.None;
                e.Node.NavigateUrl = null;                
            }
        }


Please advise.

You need to make your sitemap provider folder aware:
//add to your app_code folder
public class FolderAware_XmlSiteMapProvider : XmlSiteMapProvider
{
    public override SiteMapNode CurrentNode
    {
        get
        {
            SiteMapNode currentNode = base.CurrentNode;
            if (currentNode == null)
            {
                HttpContext context = HttpContext.Current;
                if (context != null)
                {
                    string text = context.Request.RawUrl.ToLowerInvariant();
                    int index = text.IndexOf("/default.aspx");
                    if (index != -1)
                    {
                        currentNode = FindSiteMapNode(text.Substring(0, index));
                        if (currentNode != null && !currentNode.IsAccessibleToUser(context))
                        {
                            currentNode = null;
                        }
                    }
                }
            }
            return currentNode;
        }
    }
}
 
//on your web.config:
		<siteMap defaultProvider="FolderAware_XmlSiteMapProvider" enabled="true">
			<providers>
				<clear/>
				<add siteMapFile="Web.sitemap" name="FolderAware_XmlSiteMapProvider" type="FolderAware_XmlSiteMapProvider"/>
			</providers>
		</siteMap>

I have already tried that and it doesn't work.  The call to FindSiteMapNode always returns null.

make sure the paths don't finish in /.

if that doesn't work, send us your site map..

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

The paths in my sitemap do indeed finish with /.  That's perfectly legitimate.

In fact if ones makes a request for site.com/folder then IIS will redirect the browser to site.com/folder/ and only then will this sencond request, for /folder/, result in /folder/default/aspx being executed.


Nevertheless, tonight at home I shall try the new sitemap provided without trailing slashes in my sitemap, and will revert.

Cheers

Really great stuff.  Works almost perfectly.  The last little niggle - how to I ensure that the node for the home page works?  In my site map it used to have this:

 <siteMapNode url="~/default.aspx" title="MySite.com" description="Home page">


I want this node, too, to work as all the others.  I have tried url="~/" and url="http://mySite.com" and url="~" but the bread crumb and tree view dislike all of these.  Is there a secret I'm missing?


Many thanks

umm the only thing i can think of is the setup of your treeview... with the very simple version attached, i managed to get Home on the breadcrumb and also the treeview..
//the sitemap:
<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
    <siteMapNode url="~/default.aspx" title="Home"  description="">
      <siteMapNode url="~/one" title="One"  description="" >
        <siteMapNode url="~/one/child" title="One child"  description="" />
      </siteMapNode>
    </siteMapNode>
</siteMap>
 
//the pages:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" />
        <asp:SiteMapPath ID="SiteMapPath1" runat="server" >
        </asp:SiteMapPath>
        <div style="float: left; width: 250px">
            <asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1">
            </asp:TreeView>
        </div>
        <div style="float: left;">
            <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
            </asp:ContentPlaceHolder>
        </div>
    </div>
    </form>
</body>
</html>

Not to worry.  I'll just use the fully qualified absolute URL for the home node.
