    Hi ,
    when i am using the RadTreeview i am facing the following error,


    Sys.ArgumentException: Cannot deserialize. The data does not correspond to valid JSON.

    Parameter name: data


    The exception is thrown after all page events are executed properly and the Microsoft Ajax Library tries to deserialize the object. (


    function JavaScriptSerializer$deserialize)




    This bug has been found in the following browsers : Cassini, IE8, Firefox, Chrome, Safari, Opera.

    could any one know the fix for this ? or  Could you please direct me to solve this issue ?
    Iam using the telerik's version : Assembly Telerik.Web.UI.dll, v4.0.30319





    Note: I am using this control in a  update panel

    Thanks & Regards,
