How to minimize viewstate size of a page in asp.net?

Question

How to minimize viewstate size of a page in asp.net? Please help.

Answer 1

   protected override PageStatePersister PageStatePersister
    {
        get
        {
            return new SessionPageStatePersister(this);
        }
    }

add the above code in the code behind of the page that generates large viewstate values. This allows storing the viewstate in the session. Only a key for the viewstate should be added now.
