----------------------------------------------------------- New Message on BDOTNET
----------------------------------------------------------- From: asksalil Message 2 in Discussion Hi Arijit, One possible cause could be: when the ASP.NET runtime generates the viewstate, it also creates a hash of the entire viewstate string, and stores this on the server. It then checks on postback to ensure that the viewstate has not been tampered with by comparing the previously stored viewstate hash, and the hash of the viewstate on the posted-back page . This is an added bit of security that ASP.NET offers, and is enabled by default.. The error you describe above could possibly occur if you wrote to the hidden viewstate field using client-side scripting- this would render in the viewstate invalid. Are you using any javascript which could be writing to the hidden viewstate field? hope it helps you Thanks & regards Salil ----------------------------------------------------------- To stop getting this e-mail, or change how often it arrives, go to your E-mail Settings. http://groups.msn.com/bdotnet/_emailsettings.msnw Need help?
