[Solved] Create tree view from a Dictionary<string, Dictionary<string, List<string>>>

[bogus]

My model is a Dictionary<string, Dictionary<string, List<string>>> , how can i create a three level tree view from it?
Looking at the source it is obvious that i must get something like this :
R1
     C1
          O13
          O22
          O18
     C2
          O3
          O5
R2.....

Anyone have any ideas?

Where "Testing" should be setting.Key or setting.Value but I cannot seem to get it to work.

@(Html.Telerik().TreeView()
    .Name("TreeView")
    .BindTo(new[] { (ConfigurationLevel) ViewBag.Preview }, mappings =>
    {
        mappings.For<ConfigurationLevel>(binding =>
            binding.ItemDataBound((item, level) => { item.Text = level.Name; })
                .Children(c => c.Settings)
                .Children(c => c.Children.Values)
            );
        mappings.For<SerializableDictionary<string, string>>(binding =>
                binding.ItemDataBound((item, setting) => { item.Text = "Testing"; })

            );
    })

)

I also tried to change the SerializeableDictionary<string, string> to KeyValuePair<string, string> but that doesn't work... I know I'm missing something but it's Friday and it's not clicking.
