[Solved] Binding to Model Using .ItemDataBound Not Working!

[Darin]

This code:

@{Html.Telerik().TreeView()
    .Name("TreeView")
    .BindTo((IEnumerable)Model, mappings =>
    {
        mappings.For<NavigationTreeNode>(binding => binding
                .ItemDataBound((item, node) =>
                {
                    item.Text = node.ShortTitle;
                    item.Expanded = true;
                })
                .Children(node => node.Children));
    });
}

Produces only this output:

• Item 1
  • Sub item 1
  • Sub item 2
  • Sub item 3
  • Sub item 4
• Item 2
• Item 3
• Item 4

Why?

Thanks, Darin

Hi Darin,

Could you please share us more details about the problem you have ? In order to assist you I will need code snippets used for the model,controller and the view or a sample project. Also please give an example what should be the expected result.
Thank you for the assistance and the cooperation.

All the best,

Controller:

    public class HomeController : Controller
    {
        //
        // GET: /Home/
 
        public ActionResult Index()
        {
            return View(NavigationTree.Root.Children);
        }
 
    }

Model:

    public class SiteMapViewModel
    {
        public IEnumerable<NavigationTreeNode> Nodes { get; set; }
        public NavigationTreeNode SelectedNode { get; set; }
 
        public SiteMapViewModel()
        { 
        
        }
    }

    public class NavigationTreeNode
    {
        public int Id { get; protected set; }
        public int ParentId { get; protected set; }
 
        public string Title { get; protected set; }
        public string ShortTitle { get; protected set; }
        public string FileName { get; protected set; }
        public string Permalink { get; protected set; }
 
        public bool RouteByTreePath { get; protected set; }
        public bool RouteByPermalink { get; protected set; }
        public bool ShowInNavMenu { get; protected set; }
        public bool ShowInSiteMap { get; protected set; }
 
        public int SortOrder { get; protected set; }
 
        public string ControllerName { get; protected set; }
        public string ActionName { get; protected set; }
 
        public bool Active { get; protected set; }
        public bool Locked { get; protected set; }

...

View:

@model IEnumerable< NavigationTreeNode>
@using Sunstone.WebSite
@using Telerik.Web.Mvc.UI
@using System.Collections
 
@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}
@{Html.Telerik().TreeView()
    .Name("TreeView")
    .BindTo((IEnumerable)Model, mappings =>
    {
        mappings.For<NavigationTreeNode>(binding => binding
                .ItemDataBound((item, node) =>
                {
                    item.Text = node.ShortTitle;
                    item.Expanded = true;
                })
                .Children(node => node.Children));
    });
}

I take it back - I did not figure this out.  For some reason, it just will not bind to the treeview.

Any help is appreciated.
