    Disconnect Error

    I have suddenly begun getting error messages on multiple pages as
    follows. I tried researching, but the issue seems quite confusing...or
    perhaps just over my head. Could someone please advise what this means
    and if there is a way to fix it. I have tried adding
    EnableViewstate MAC="false" in the page declaration with no success.
    Again, it does not appear to be consistent.
    I'm using ASP.NET 2.0 with IE7.

    THANKS!

      Re: Disconnect Error

      there are three steps in saving viewstate

      1) serialize to buffer
      2) encrypt buffer (prevent hacking) mac address effects this
      3) base64 encode buffer (make binary into a 7bit char string)

      reading is the reverse. you are getting an error on the base64 decode. a
      base64 string has a fixed set of characters (a-z) (A-Z) "+", "/" and
      "=". its length must be a multiple of 3.

      the error means the viewstate value sent to the browser is not the value
      the browser is sending back. a common cause is a proxy server that
      truncate the value. if you are sending over 1k of viewstate you should
      change you usage of viewstate.

          Re: Disconnect Error

          Thank you, Bruce. I am using a dedicated host server. Can I change the
          setting to not truncate the viewstate? If so, could you please point me
          in the right direction?

          Also, what is the alternative for viewstate? For example, a gridview
          upon postback. How would I keep that current? I'm not sure the less than
          1K is feasible for my purposes...but its clear you know much more than I
          about this. Would you mind giving me more information?

          Thanks again!
          Kit
