    Hi

    I am trying to use RadTreeView in my web application. I am trying to add nodes from code behind. I am getting following error whe n I try to run the application and TreeView gets frozen not able to expand or do anything in the page. I have a login page for the web application I am not sure if this is causing the problem because when I use the treeview in a web application which does not have authentication it works fine.

    Microsoft JScript runtime error: Sys.ArgumentException: Cannot deserialize. The data does not correspond to valid JSON.
    Parameter name: data


    Any help to fix this error or debug why this error is coming.

    Regards
    Kiran
