public ObservableCollection <Model> name_of_object {get; set; } = new ObservableCollection <Model> ();

As the document you refered about TreeView, the Data binding to the ItemsSource property on TreeView and TreeViewItem is in Insider Preview build and SDK. You can follow the document Tree view using data binding part to achieve this function, but you should install the latest Windows 10 Insider Preview build and SDK, target you app on the insider preview build and test it in the insider preview build OS device.
