MSDN documentation says that the page object has a Viewstate property too (the page class inherits from Control). I don't know how this renders in HTML, but it seems that you could store a page variable there. The difference between storing state in Viewstate or Session is just a matter of whose resources you want to tax. If you store state in Session, you are taxing the web server. If you store in Viewstate, you are taxing the bandwidth and the client's memory.
