Hi Philip Saltskog,
Controls are supported by RadTreeView and the best approach is to use Templates.
Regarding your case, without additional information I will be unable to determine why Templates do not work as expected at your side.
Could you please open a formal support ticket and send us the problematic pages (or project) there (including the second issue you are experiencing)?
We will inspect the files and hopefully will provide solutions or temporary workarounds.
Thank you in advance for your co-operation.
