title: How to get the value of a parameter of an actionResult in another actionResult of the same controller?
body: <p>It is about the implementation of the reservation in a restaurant.
  My structure is as follows. On the home page the customer can click on the restaurant in which he wants to reserve, the system displays the details of this restaurant (with the id which is passed in parmetre. Id which I will wish to recover thereafter)</p>
  <p>And on this page the customer can click on the reservation button to go to the reservation form page. I would like the drop-down list of restaurants that is contained in this form to automatically point to the restaurant with which has the previous id.</p>
  <p>Or at least if I can retrieve the id I will retrieve its value in the form validation controller and so I can assign the restaurant that corresponds to the reservation before registering the reservation.</p>
