[Solved] Changes to MVC Menu in Q2 Release

[Jamie]

Something broke when I upgraded form the Q1 release to the Q2 release of the MVC Menu.

Under the hood, I have the following object representing my menu:

    [Serializable()]
    public class Menu : List<MenuItem>
    {
    }
 
    [Serializable()]
    public class MenuItem
    {
        public long ItemId { get; set; }
        public string Text { get; set; }
        public string Type { get; set; }
        public string Url { get; set; }
        public long ObjectId { get; set; }
        public Menu Children { get; set; }
        public bool Selected { get; set; }
        public MenuItem()
        {
            Selected = false;
        }
    }

I have the following code that worked prior to upgrading:

@{
    MySite.Menu menu = ViewBag.Menu;
}
@if (menu != null)
{
    Html.Telerik().Menu().Name("SiteMenu").BindTo(menu, mappings =>
    {
        mappings.For<MySite.MenuItem>(binding => binding
          .ItemDataBound((item, menuItem) =>
          {
              item.Text = menuItem.Text;
              if (menuItem.Url != null) item.Url = menuItem.Url;
              item.Selected = menuItem.Selected;
          })
          .Children(menuItem => menuItem.Children)
        );
    });
}

I use the Telerik CDN, so my stylesheets and javascript are correct for the version:

<script type="text/javascript" src="http://aspnet-scripts.telerikstatic.com/mvcz/2011.2.712/telerik.common.min.js"></script>
<script type="text/javascript" src="http://aspnet-scripts.telerikstatic.com/mvcz/2011.2.712/telerik.menu.min.js"></script>

It appears that the problem is that the actual HTML markup is not being output in the page. Not even the SiteMenu div.

I tried looking through the release notes, but I didn't see anything that should have changed.

Hello Dave,

 
After quick review of the code snippet I noticed that you are using Menu UI component in a code block without calling the Render() method. Thus the component will not be rendered. Check the attached test project. I have test the provided code snippet with Q1 version and the menu does not render if there is no Render() method.
