The child nodes are aligned to the root nodes when ShowRootLines property is set to false.
Hello,
This reported behavior is not reproduced with the latest Q2 2026 (2026.2.520) version of the Telerik UI for WinForms.
This is why I will close this item and set its status to "Declined" on our feedback portal. Please upgrade to the latest version to take advantage of the improvements in the RadTreeView component.
Regards,
Nadya | Tech Support Engineer
