.NET ViewState Decoder
Top  Previous  Next

As you can see below, the view state decoder for reading the hidden viewstate on an ASP.NET Page. The ViewState Decoder will display the hidden ViewState in a treeview, rawtext, or in XML format. Please refer to "http://msdn.microsoft.com/en-us/library/ms972976.aspx" to find more information about ASP.NET View state.

Please Note that ViewState is MAC (message authentication check) encoded to prevent tampering by remote clients. As such, while you can decypher the viewstate settings using the above program, you can't actually change them and repost to the server. You can also set a stronger level of ViewState to prevent the above decoder from working by changing your encryption key settings in either machine.config or web.config.
