    I have been looking into your question, however, what I can say is that UltraWebTree is retired and not available in the currently supported version of our product.

    Having this in mind, what I could suggest is to update to the latest version and test the behavior with the WebDataTree control which is the replacement of the UltraWebTree in the newer toolsets.

    Let me know if I may be of any further assistance.
