Please refer to the attached gif file and sample project. The screen tip position is not the same each time. Hence, the issue may not be reproducible every time. Workaround: use the TooltiptextNeeded event.
Hello,
This behavior does not reproduce in the latest Q3 2026 version. This is why I marked this thread as "Declined" on our feedback portal.
Please upgrade to the latest version to take advantage of the improvements in the RadTreeView component.
