MVCSitemapProvider

[Simon]

Hi All,

This is my first post so go easy on me :)

I'm trying to integrate Telerik Menus into my MVC2 application.

I'm using:

VS2010 Ultimate
ASP.Net MVC 2 (.Net 4 in VB)
Telerik MVC DLL Ver 2010.2.825.235

My site uses the MVCSitemapProvider available here: http://mvcsitemap.codeplex.com/

MVCSitemapProvider exposes itself as a standard sitemap provider to ASP.Net MVC and also as an "MVCSitemap" through an MVCSitemapProvider namespace. It reads .mvcsitemap files (example below)

<?xml version="1.0" encoding="utf-8" ?>
<mvcSiteMap xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-2.0" enableLocalization="true">
    <mvcSiteMapNode title="Root" controller="Root" action="Root" changeFrequency="Always" updatePriority="Normal">
        <mvcSiteMapNode title="Login" controller="Public" action="Login" />
        <mvcSiteMapNode title="Admin" controller="Admin" action="Index">
            <mvcSiteMapNode title="Statistics" controller="Admin" action="Statistics" />
        </mvcSiteMapNode>
        <mvcSiteMapNode title="Home" controller="Home" action="" />
    </mvcSiteMapNode>
</mvcSiteMap>

I need to load the sitemap output from  MVCSitemapProvider into a Telerik menu and I just don't seem to be able to work out how I should do it.

I've tried: recursively iterating through the sitemap and building Telerik UI MenuItems into the appropriate structure (this works fine) but I don't know how to bind that structure to the menu on the page (and the only demo I can find was for ASP.Net assuming a menu control which could be accessed from a code-behind?)

I've also tried using the

        SiteMapManager.SiteMaps.Register(Of XmlSiteMap)("examples", Function(sitemap) sitemap.LoadFrom("/Web.sitemap"))

syntax in Global.asax but I can't work out how to cast the sitemap into the appropriate type (and I definitely don't want to load from file as I don't have a "normal" sitemap)

Can someone please tell me how to bind this? If you need more information, just let me know

Many thanks

Hello Simon,

If you have create a collection of MenuItem object, then you just need to bind the menu to them. Check this help topic which shows how to do this.

Kind regards,

Html.Telerik().Menu()
    .Name("Menu")
    .BindTo(Html.MvcSiteMap().Provider.RootNode.ChildNodes,
        mappings => mappings.For<MvcSiteMapNode>(binding => binding
            .ItemDataBound((item, node) =>
                {
                    item.Text = node.Title;
                    item.ActionName = node.Action;
                    item.ControllerName = node.Controller;
                })
                .Children(node => node.ChildNodes)))
    .Render();

I use this piece of code to bind to my MvcSiteMap.

Thank you both for your responses - especially the code snippet from Jann, it was very helpful and did solve my problem

Cheers

I am in an MVC 3 Razor environment and Jann's code does not work for me. What using statements if any are you including in your view?

After fighting with it for awhile I finally got the "are you missing an assembly reference?" errors to go away but then got a null reference error.

Are there any additional assumptions I should be aware of in order to get this code to work. I too am trying to get the MVC Sitemap provider to work with telerik menu.

Hi the only update I had to make to the code above is to repplace the assignments to item.ControlelrName and item.ActionName into

item.Url = Url.Action(node.Action, node.Controller, new {node.Area});

 I use the following include besides the Telerik include:

<%

@ Import Namespace="MvcSiteMapProvider" %>

i have noticed one problem with this approach. when my site hierarchy is deeper than 2 levels the menu will only show the path containing the controller and action, yet i want it to display the full path such as all 3 items in the nested hierarchy. for example based on the following sitemap when i hover over the menu item it shows:

about-us/john-smith  instead of about-us/team/john-smith

<mvcSiteMapNode title="About Us" controller="AboutUs" action="Index">
  <mvcSiteMapNode title="Team" action="team">
    <mvcSiteMapNode title="John Smith" action="john-smith">
  </mvcSiteMapNode>
</mvcSiteMapNode>

[darenkov]

that is fine but what if you have hierarchy with 3 levels or more and want to show the 3 levels in the path selection, ie

one/two/three

Hi,

I've also used Jann's example and am able to build/publish without error.  However, when I view the site in browser, an error comes up on the line with the Render command:

@using Telerik.Web.Mvc.UI;
@using MvcSiteMapProvider;

@(Html.Telerik().Menu()
    .Name("Menu")
        .BindTo(Html.MvcSiteMap().Provider.RootNode.ChildNodes,
            mappings => mappings.For<MvcSiteMapNode>(binding => binding
                .ItemDataBound((item, node) =>
                {
                    item.Text = node.Title;
                    item.ActionName = node.Action;
                    item.ControllerName = node.Controller;
                })
                    .Children(node => node.ChildNodes)))
        .Render();

)

Can anyone suggest how I'd rectify the error message  CS1026: ) expected

Thanks,
Sid
