Unable To Validate Data Encryptordecryptdata
Go to Solution 2 Comments LVL 58 Overall: Level 58 ASP.NET 14 Message Accepted Solution by:amit_g2005-02-19 That happens because the key used to encrypt/decrypt view state got changed. By "hard coding" this value in your web.config, the key that asp.net uses to serialize and deserialize your viewstate stays the same, no matter which server in a server farm picks at System.Web.Configuration.MachineKeySection.GetDecodedData(Byte buf, Byte modifier, Int32 start, Int32 length, Int32& dataLength) at System.Web.UI.ObjectStateFormatter.Deserialize(String inputString) HttpApplication.RaiseOnError => EventHandler.Invoke => Global.Application_Error This is being caught in my global.asax.
