    <p>Invalid postback or callback argument.  Event validation is enabled
    using  in configuration or &lt;%@
    Page EnableEventValidation="true" %> in a page.  For security
    purposes, this feature verifies that arguments to postback or callback
    events originate from the server control that originally rendered
    them.  If the data is valid and expected, use the
    ClientScriptManager.RegisterForEventValidation method in order to
    register the postback or callback data for validation.</p>
