Asp Net Unable To Validate Data
This is being caught in my global.asax. I've searched around but can't find the cause. This exception is being thrown in extremely simple and small webforms. The site is not hosted within a webfarm. 2 pages seem to cause this error intermittently and one of them stores a bool in the ViewState, but it is not modified apart from that. Has anyone come across this before? asp.net exception share|improve this question edited Dec 16 '15 at 17:12 Juan C. 2,47911427 asked Apr 29 '09 at 15:33 Ciaran O'Neill 1,31852434 add a comment| 5 Answers 5 active oldest votes up vote 10 down vote accepted http://dotnetcoderoom.wordpress.com/2008/11/07/unable-to-validate-data-aspnet-error/ Cause: The basic reason of this is the difference of key while encrypting and decrypting the viewstate data. Suppose an asp.net rendered a page with key1 and saved the page state in view state, meanwhile asp.net’s key is changed to key2, now when some server side event will occur on page the viewstate will get decrypted and this error will occur as the old view state is now not valid due to a different encryption key. It may occur when you open a page for along time and after that do some e

GuidanceSamplesVideos Reply Ergole None 0 Points 2 Posts Re: Unable to validate data, EncryptOrDecryptData problem Feb 05, 2014 12:14 PM|Ergole|LINK Ok so we finally http://stackoverflow.com/questions/802921/what-does-an-unable-to-validate-data-exception-in-system-web-configuration-mac found what was happening. The Framework .NET 4.5 changed the way in which IIS validate the Webresource.axd requests. Before 4.5, a Webresource.axd?d=AAA&t=XXX request worked all the time (even if the machinekey changed on the server). Now, if you make this request, restart your application pool (so it renew https://forums.asp.net/post/5620791.aspx the machinekey if you've let default configuration "Autogenerate" for machinekeys... as we had), and make the same request a second time : you'll get the error. So our problem was that some Webresource.axd requests are cached by browsers (we didn't knew that...) but our machinekeys changes. Now what we have to do : Fix the machineKeys in Web.config and wait for all our users to clean their browser cache. Microsoft... Why do you never advise developpers when you change such a big thing ???????? By "advise" I mean explaining clearly what are the consequences of the change !!! httpException asp.net webresource.axd This site is managed for Microsoft by Neudesic, LLC. | © 2016 Microsoft.

Aug 28, 2006 08:04 AM|miglas|LINK I am getting this error on unable to a windows 2003 productionserver of my asp.net application. I can't replicate it on my Windows XP professional IIS 5.5 server. It seems like its happeningduring postbacks. I have a login page and when I try to log on to the private pages this error happends. I already read some forums about the errorand they suggestchanging unable to validate the enableViewStateMac property of the asp.net pages to true. I already try it <%@ Page enableViewStateMac="true" ... %> but the problem persist! This only recently started happening all of a sudden andI can't figure out what is causing this,I never had this problem in other asp.net applications that I developed. Any help would be greatly appreciated. Thanks Miglas PS - This is the exact error message:
