I juts can't get the xamdatatree binding working. I attached a demo program. It is easy to set up the wpf Treeview hierarchy using templates and I am looking someting similar to use in xamdatatree.
Thanks
Hello,
I am just checking if you got this worked out or you still require any assistance or clarification on the matter.

You would need to change your collections from ObservableCollection<ItemBase> to ObservableCollectoin<School> and <Subject>
when the datamanager is processing the collections, it asks for the type of objects that are in it from the collection itself. in your case its seeing ItemBase objects and trying to find a node layout for that.
