Question

Passing data from a controller to another controller. this is what i am doing, but I dont think it is the correct way of doing it, plz help me modify the code for it to work, share example/tutorial..

e.g

I am using Membership API to create a user account

public ActionResult Register() { return View(); }

[HttpPost]
public ActionResult Register(RegisterModel model)
{
  //creates an account and redirect to CompanyController
  //Also I want to store the userId and pass it to the next controller, I am using a session, ok? 
  Session["userObject"] = userIdGenerated()
  return RedirectToAction("Create", "Company");          
}

CompanyController:

public ActionResult Create() { return View(); }

[HttpPost]
public ActionResult Create(CompanyInformation companyinformation)
{
   //creating company account and I need to store the userid to the company table retrieving from a session
   companyinformation.UserID = Session["userObject"].ToString();
   db.CompanyInformation.Add(companyinformation);
   db.SaveChanges();

   //retrieving companyId that was generated and need to pass to the next controller I tried to use "TempData["companyId"] = companyinformation.CompanyInformationID" But the data is no longer found on httpPost

return RedirectToAction("Create", "Contact");

}

Contact controller

  public ActionResult Create()
  {
   //I tried using ViewBag to store the data from TempDate but the data is no longer found on httpPost
        ViewBag.companyId = TempData["companyId"].ToString();
        return View();
   }

 [HttpPost]
 public ActionResult Create(CompanyContact companycontact)
 {
     companycontact.CompanyInformationID = ???? How do I get the companyId?
     db.CompanyContacts.Add(companycontact);
     db.SaveChanges();
    //Redirect to the next controller...
 }

I hope it is clear what I am trying to do. Maybe use ViewModels but I am not sure how to put it together… Thanks!

You can pass your UserID parameter directly to your controller’s method as it was a standard navigation flow

RedirectToAction has one overload that allows you to set routeValues.

  return RedirectToAction("Create", "Company", new { id = userIdGenerated() });    

And in your CompanyController

public ActionResult Create(int id) { return View(id); }

Since you will have your id in the URL, then you would be able to catch it in your post as well:

[HttpPost]
public ActionResult Create(int id, CompanyInformation companyinformation)

Or you can persist it into the model CompanyInformation on GET Create
