There was such an issue with the RadTreeView
but we fixed it with the latest official release - Q1 2011 SP1. Is this the version you use in your appliaction? If not, can you give ti a try and let us know if it fixes your issue?
However, if you can reproduce the selection problem with the Q1 2011 SP1 release, we will appreciate it if you can elaborate more on your scenario or send us a sample project illustrating it, so that we can try to reproduce the issue on our side and investigate what is causing it. Thank you in advance for your cooperation.
