    Hello,

    We are not aware of such known behavior in RadListBox but it looks like you are trying to serialize one of its not serializable types. You can refer to this forum thread where an explanation to this error is provided.

    If you still can't figure out what is causing the issue please share the code that you are using connected with RadListBox s owe could inspect ti and be more helpful.
