ASP SitemapPath Not rendering correctly

Posted by Community Admin on 02-Dec-2010 00:00

Since there is no longer a breadcrumb control in sitefinity 4.0 i made a quick custom control that is just has an asp sitemappath in it. There are two issues i am running in to.

1) no matter what the current node does not get rendered on the page. I found that it is not putting anything between the <a></a> tags for the current node, the href part is rendered fine but there is no text

2) In both firefox and safari the links are not clickable, IE is fine both 7 and 8. I found this to be true in 3.7's breadcrumb control as well.

Thx
Michael

Hello Michael,

Can you try using this control

<asp:SiteMapPath runat="server" ID="SiteMapPath1" RenderCurrentNodeAsLink="true" PathSeparator=">" ></asp:SiteMapPath>

It is rendering the nodes as links at my end.

Kind regards,

I tried it in a blank template, and it works to render the links as clickable, so i'm thinking i might have something off in my css for the masterpage.

But i still have the problem of the Current Node Not Being Rendered.

Hi Michael,

Can you show the code you use? My code above renders all nodes and includes the current one.

sure... Mine has some custom stuff to it, but i tried it with the code you posted above and it behaves the same way for me.

i made a user control called Breadcrubs.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Breadcrumbs.ascx.cs" Inherits="SitefinityWebApp.Controls.Breadcrumbs" %>

<asp:SiteMapPath runat="server" ID="SiteMapPath1" RenderCurrentNodeAsLink="true" PathSeparator=">" ></asp:SiteMapPath>

code behind is

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

namespace SitefinityWebApp.Controls

public partial class Breadcrumbs : System.Web.UI.UserControl

protected void Page_Load(object sender, EventArgs e)

protected override void OnInit(EventArgs e)

base.OnInit(e);

SiteMapPath1.SkipLinkText = String.Empty;

SiteMapPath1.ItemCreated += new SiteMapNodeItemEventHandler(Breadcrumb_ItemCreated);

protected void Breadcrumb_ItemCreated(object sender, SiteMapNodeItemEventArgs e)

//hide the root node, and it's following path separator

if (e.Item.ItemIndex == 0 | (e.Item.ItemIndex == 1 && e.Item.ItemType == SiteMapNodeItemType.PathSeparator))

e.Item.Visible = false;

then i added it as a control using these steps:
www.sitefinity.com/.../controls-adding-a-new-control.html

and then i add it to my template page.

Hello Michael,

I checked the control with a local project and the current node was rendered correctly at my end. I do not see any problem with this code. There is some other logic that breaks it. Also, this is the standard ASP.NET SiteMapPath control which just added on a page ( without any server side code) displays all nodes properly.

Hi,

Experiencing the same issues with current page not showing and also the root link reads Page not Home as expected.

Hello Neil,

Pages is the StartingNode of the SiteMap. If you use the code above where Michael subscribes for Breadcrumb_ItemCreated, you cannot see Page, because it is explicitly hidden. I am sending you a short video. This is the standard ASP.NET control and of course there could be some improvements to it.

Thanks Ivan,

I queried the breadcrumb in 3.7 and was pointed to adapters, the adapter implemented does not work in 4 and fails at collection.Add(node) value cannot be null.

protected override void RenderContents(HtmlTextWriter writer)

writer.Indent++;

SiteMapPath item = (SiteMapPath)Control;

SiteMapProvider Provider = ((System.Web.UI.WebControls.SiteMapPath)(Control)).Provider;

SiteMapNodeCollection collection = new SiteMapNodeCollection();

SiteMapNode node = Provider.CurrentNode;

if (node != null)

collection.Add(node);

while (node != Provider.CurrentNode.RootNode)

node = node.ParentNode;

collection.Add(node);

BuildItems(collection, true, writer);

writer.Indent--;

writer.WriteLine();

Hi Neil,

It is failing at this line most probably:

if (node != null)

collection.Add(node);

while (node != Provider.CurrentNode.RootNode)

node = node.ParentNode;

collection.Add(node);

Please try getting the current node using the bellow code instead of the one you are currently using:

SiteMapNode currentNode = SiteMapBase.GetCurrentProvider().CurrentNode;

Hello,

I'm also having the same problem where the current node is not being rendered. On all pages and subpages, Telerik.Sitefinity.Web.PageSiteNode.Title is an empty string.

As for setting the root node text to "Home", I'm reverting to:

void smp_Breadcrumbs_ItemCreated(object sender, SiteMapNodeItemEventArgs e)

if ((e.Item.ItemType == SiteMapNodeItemType.Root) && (e.Item.Controls.Count > 0))

if (e.Item.Controls[0] is HyperLink)

((HyperLink)e.Item.Controls[0]).Text = "Home";

I've searched around but couldn't find a way to set the sitemap root title via Sitefinity settings. Did I miss something?

Hi Ed,

You have to use an instance of PageNode which has a property Page.Title which is the name of the page.

var pageNode = _SiteMapNode as PageSiteNode;

var pn = man.GetPageNode(pageNode.Id);

Best wishes,

So, this is how I accomplished changing the root "Pages" text to "Home", in addition to rendering the current node...

void smp_Breadcrumbs_ItemCreated(object sender, SiteMapNodeItemEventArgs e)

if ((e.Item.ItemIndex == 0) && (e.Item.ItemType == SiteMapNodeItemType.Root) && (e.Item.Controls.Count > 0))

if (e.Item.Controls[0] is HyperLink)

((HyperLink)e.Item.Controls[0]).Text = "Home";

((HyperLink)e.Item.Controls[0]).ToolTip = "";

else if (e.Item.ItemType == SiteMapNodeItemType.Current)

if (e.Item.Controls[0] is Literal)

Telerik.Sitefinity.Web.PageSiteNode pageSiteNode = (Telerik.Sitefinity.Web.PageSiteNode)e.Item.SiteMapNode;

Telerik.Sitefinity.Modules.Pages.PageManager manager = new Telerik.Sitefinity.Modules.Pages.PageManager();

Telerik.Sitefinity.Pages.Model.PageNode pageNode = manager.GetPageNode(pageSiteNode.Id);

((Literal)e.Item.Controls[0]).Text = pageNode.Title.Value;

Hopefully, there's a more efficient way to do this?

Thanks,
Ed Sirijintakarn

thx ed. That worked for me.

Does anyone else's Home link display twice when they are actually on the Home page using this code?

I get a linked Home and then an unlinked Home...almost like it's not recognizing that it's at the root level.

Posted by Community Admin on 31-Jan-2012 00:00

Hi
I am getting Home twice..
do you know how to fix it?
Thanks,
