I have a pure object model that looks like this:

[Serializable]

public class NavigationModel

{

private IList<App> _applications;

public IList<App> Applications

{

get { return _applications; }

set { _applications = value; }

}

Each App contains an IList of Features. I want to map this object model to the menu control. Right now I have hierarchy through the object model and I want to keep it this way. How would I do this?

Here is some of what I have tried with no success:

_navigationModel = _navigationService.LoadData();

TopMenu.DataSource = _navigationModel.Applications;

TopMenu.DataFieldID = "Id";

//TopMenu.DataMember = "Applications";

//TopMenu.DataTextField = "Name";

//TopMenu.DataValueField = "RelativePath";

TopMenu.Flow = ItemFlow.Horizontal;

RadMenuItemBinding appBinding = new RadMenuItemBinding();

appBinding.Depth = 1;

appBinding.TextField = "Name";

appBinding.ValueField = "RelativePath";

appBinding.DataMember = "Features";

TopMenu.DataBindings.Add(appBinding);

TopMenu.DataBind();

Thanks

I redesigned my objects and now I have the menus displaying flat (no hierarchy). The code i have is below. Do you see any reason why it wouldn't be rendering properly?

aspx:
    <telerik:RadMenu ID="TopMenu" Runat="server" />

model:
    public class NavigationModel
    {
        protected int _id;
        protected string _name;
        protected string _description;
        protected int? _parentId;
        protected string _relativePath;

        public int Id
        {
            get { return _id; }
            set { _id = value; }
        }

        public string Name
        {
            get { return _name; }
            set { _name = value; }
        }

        public string Description
        {
            get { return _description; }
            set { _description = value; }
        }

        public int? ParentId
        {
            get { return _parentId; }
            set { _parentId = value; }
        }

        public string RelativePath
        {
            get { return _relativePath; }
            set { _relativePath = value; }
        }
    }

Code-Behind:
                TopMenu.DataFieldID = "Id";
                TopMenu.DataTextField = "Name";
                TopMenu.DataNavigateUrlField = "RelativePath";
                TopMenu.DataFieldParentID = "ParentId";
                IList<NavigationModel> navigationModel = _navigationService.LoadData();
                TopMenu.DataSource = navigationModel;
                TopMenu.DataBind();

I got it fixed by adding the following to my web.config:
