FIX. RadTreeView - setting nodes Visible = false results in invalid state of the scrollbar

To reproduce:


Add nodes to RadTreeView with at least 3 levels hierarchy. Set some of the last level nodes Visible property to false. Start the application. Expand some nodes and scroll. You will notice that the last item will change sometimes.


Workaround:
Set this.radTreeView1.TreeViewElement.AllowArbitraryItemHeight = true;
Use ItemHeight = 1, instead of Visible = false

Hello,

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,
