Multi-page wizard in MVC - where to store the entered data

Question

What do you think it's the best way to create a wizard over several pages in asp.net-mvc ? I am thinking to:

1. create a hidden field in every page which contain my whole object serialized
2. override OnActionExecuting -> get my object from the hidden or tempdata
3. override OnResultExecuted -> put the object in tempdata, when i go to the next page(when redirect)

Answer 1

1. Wrap each step in the wizard in some <form> element
2. Do a form submit when going to the next step (either through javascript or via <input type='submit'>
3. Handle the form-post to extract the data inserted by the user
4. Store your previously stored answers in a Session variable, and retrieve the object when in the form-post
5. Add the new answers, and re-save the object in Session
6. When finishing, retrieve the object, and persist the settings.

Just have some

[Serializable]
public class WizardAnswers

which contains properties for each wizard-answer to save the user's data in.
