My data hierarchy has a single root node. It is always single and always the same.
Is it possible just to hide it and show only items starting from the second level?
If your RadTreeView is databound, just pass the second level collection of business objects (ViewModels)
as an ItemsSource of the tree.
If the tree is defined declaratively, you have to edit the template of the root RadTreeViewItem and make its HeaderRow have Height and MinHeight set to 0. You can find this approach realized in the attached solution.
Best wishes,
