I am receiving an Invalid ViewState error after posting back to the same page
twice. Consistently the error occurs after the second postback and not after
the first.
I have looked into creating a static machinekey in the machine.config and
that did not help. I believe that issue only occurred when there was an
inconsistent viewstate error. The error I am faced with consistently occurs.
Are there any known problems with the ViewState when posting back to the
same page multiple times? Any help would be much appreciated. 9 4832
Jamie,
What's the exact error being returned?

Unfortunately I have already tried setting the EnableViewStateMac attribute =
"false" and it did not fix the issue. Also, I am not using Server.Transfer
on the page.

Jamie,
Is it possible for you to post the code or at least the parts of it or an
example that you deem relevant? It's going to be almost impossible to figure
out what's going on without seeing an example.

Alvin,
I had seen this article and tried some of the suggestions such as using a
static machinekey, but that did not work. Also, the error is not
intermittent as it always occurs after the second postback of the page. I am
running this on a local IIS server which does have virus protection although
I don't think this would be an issue since the postback works fine the first
time.
Is there anything related to viewstate and multiple postbacks where I have
to issue some type of clear statement to the page? The only solution I can
think of is to eliminate the use of ViewState altogether.
