Could you please clarify whether the child elements should have a different style or different fields. Or maybe both?
From the image and table you've provided, I can assume that your hierarchy is of heterogeneous data. As stated in the RadTreeListView vs RadGridView
section of RadTreeListView's Getting Started article
, you should use RadTreeListView only when you need to display homogeneous data. For heterogeneous data, you should use a Hierarchical RadGridView
If you need your children to have a different style from their parent, you can then modify RadGridView's HierarchyChildTemplate to your liking.
Please let me know if you find this information helpful.
