Hi Charles,
Thanks for choosing Syncfusion products.
We hope you’re talking in perspective of Tools-Windows TreeViewAdv.
We tried to create a simple sample by populating a panel with more TreeNodeAdv and use the scrollbar to select the nodes. Please find the sample from the below location.
http://files.syncfusion.com/support/Tools.Windows/7.3.0.20/59583/main.htmWe are not able to reproduce any such issues as node as if we hadn’t used the scroll bars at all. Still if you could reproduce the issue. Kindly update us with a single sample to reproduce the issue from our end.
Please let us know if you have any queries.
Regards,
Bala.
