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

I left the page flow up to the view, where I believe it belongs, so different views could have different page flows (e.g. for desktop browser clients or mobile phone clients etc.) I wrote it up on my blog: A RESTful Wizard Using ASP.Net MVC… Perhaps?

Answer 3

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();
}

Answer 4

public class CreateAccountWizardController : Controller
{
   public ActionRresult Step1()
   {
   }


   public ActionResult Step2()
   {
   }
}

Answer 5

There are a couple ways, create an action for each step of the wizard process, or create a parameter that is passed in to the action method. Like step that will allow you to know what the state of the wizard is in.
