The Enabled property cannot be set in PropertyBuild if the RadTreeView is already data-binded via Property builder Workaround: Set the property at run-time.
Hi, Peter,
This issue does not reproduce with the latest Q1 2026 (2026.1.210) 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.
If you have any other questions or concerns, please do not hesitate to contact me. Thank you!
Regards,
