Which patterns should I use when I building wizard GUI (next, back, cancel)

Question

I'm drowning in switch / if / else hell. I'm trying to build wizard that hold a lot of pages and states.

I have 5 main categories and in each category I have a wizard. Now I'm doing it with zillion switch's and if's there must be better way for that. I am looking for design patterns.

Answer 1

its obvious - State

every your page can be treated as separated state

so you need state machine - some kind of:

page1 -> page2 -> page3 or page4 .... and so on
