Question

What is ViewState? How is it encoded? Is it encrypted? Who uses ViewState?

Answer 1

If you really want to understand ViewState (not just what it is used for), then you may want to read this fabulous article (which I, unfortunately, am not the author of :-). Beware, though, it is a bit dated, but still a very good read.
