    I am getting the following issue when I used the SessionPageStatePersister for saving the viewstate data in session. The stack trace does not show the detailed source of the error. What is the general cause for the issue and how can it be resolved?

    [InvalidCastException: Specified cast is not valid.]
    at System.Web.UI.SessionPageStatePersister.Load()

    Neerajan, we'll need more info.

    If you don't think ASP.net is the right place, you need to tell us why.

    Also, we'll need more info about your technology and context.

    Thanks!
