How to pass a value from a controller method to an another?

Question

I'm beginner in MVC3, and I want to get a value from an another controller's method. Here the two methods:

    [HttpPost]
    public ActionResult Create(TennisClub tennisclub)
    {
        if (ModelState.IsValid)
        {
            db.TennisClubs.Add(tennisclub);
            db.SaveChanges();
            return RedirectToAction("AssignManager");  
        }

        return View(tennisclub);
    }

    [HttpPost]
    public ActionResult AssignManager(Manager manager)
    {

    }

So, when I'm creating a new tennis club, Immediately I would like to assign a manager to it... For that I need the primary key "ID".

So my question is: How to get this ID in my "AssignManager" method ? Thanks in advance

Why dont you assign the manager right there when you add the Tennis club? — Dejan.S

You cannot redirect to an action decorated with the [HttpPost] attribute. That's not how a redirect works. A redirect means that you are sending a 301 HTTP status code to the client with the new Location header and the client issues a GET request to this new location.

So once you remove the [HttpPost] attribute from your AssignManager action you could pass the id as parameter:

return RedirectToAction("AssignManager", new { id = "123" });

and then:

[HttpPost]
public ActionResult AssignManager(int id)
{

}

Basically, you need to have a GET AssignManager method, too, which would have a parameter telling it to which TennisClub the manager should be assigned:

[HttpGet]
public ActionResult AssignManager(int tennisClubId)
{
    // here, you will want to return AssignManager view
}

And when redirecting to AssignManager from Create, you can specify the id of TennisClub:

return RedirectToAction("AssignManager", new { tennisClubId = tennisclub.Id });

return RedirectToAction("AssignManager", new { id = tennisclub.Id });

Also you need to remove the [HttpPost] attribute from your action

public ActionResult AssignManager(int id) {
  //...
}
