Viewstate Mac Error In Asp.net

Jan 26, 2006 11:56 AM|devMonky2k|LINK Hi crystal.net, I can confirm I get exactly the same error. New install worked w/o to disable the viewstate MAC. Although, it seems I was not able to repeat that result.

It reoccured later, presumably explained by the overrides to which the earlier MVP post refers, went away again after a re-boot, came back again out of nowhere because the parameters had Feb 01, 2006 04:55 AM|xpedite|LINK Mate this is not the case. How much more than my mortgage should I charge for rent? Of course, that's hard to tell your users, but perhaps you could disable the UI until the form has rendered?" that's hard to tell your users....

regards. Whilst you could edit out the relevant code from DNN, I would not recommend trying to work around this as you open yourself up to potential security issues. MSIE 5, Firefox, Safari (we capture client info for all errors so we can check this kind of stuff).

"if you guys add this to web.config, does it still reproduce?

It happens everytime someone is idle on the default page, for the session to run out, and then presses a button. I get this error even though I have disabled viewstate validation! Feb 07, 2006 05:15 AM|crystal.net|LINK thanks you both. I update my Win XP with SP3 and Other Updates.

I did _not_ play around with any default settings for any of the below-but here is what others say works (which I did not do): validateRequest="false" enableEventValidation="false" viewStateEncryptionMode ="Never" EnableViewStateMac="false" EnableViewState="false".

To suggest that the application is failing because the user is clicking the button too soon is ludicrous. if you don't use this property, you will never get that "Validation of viewstate MAC failed" error by navigating quickly (do postback before whole page has finishedrendering). I added the line attributes mentioned here to disable validation and the page no longer crashes - of course it no longer works either.

updates? But I emphasize this is probably not important at all. You can try disabling viewstate if it is 2.0 and just use controlstate. Very detailed as well..

I don't really understand this: int FormStart = html.IndexOf(">form"); int EndForm = html.IndexOf("<", FormStart) + 1; Surely FormStart will never be true, unless you mean to match "form"? We haven't seen as many of those but it certainly can cause the same problem.

But .Net should catch this for me... But there isn't a cost from us for getting this. Hope that helps someone out there.
