How do I handle page flow in MVC (particularly asp.net)

Question

If you had to provide a wizard like form entry experience in mvc how would you abstract the page flow?

Answer 1

Investigate the post-redirect-get pattern.

Use that along with a robust domain model (for tracking steps or form completion state or whatever you call it) and you're golden.

Answer 2

In order to keep the steps you could implement a page flow action filters, which provide an experience like this one:

[RequiredStep(FlowStart = true)]
public ActionResult Confirm()
{
    return View();
}

[RequiredStep (PreviousStep = "Confirm")]
public ActionResult ExecuteOrder()
{
    return RedirectToAction("ThankYou");
}

[RequiredStep(PreviousStep = "ExecuteOrder")]
public ActionResult ThankYou()
{
    return View();
}
