Question

I have a view where everything will be populated by the user – but relates to a parent entity. I pass that Id to my view using ViewBag, but I don’t know how to get it back to the post action in the controller. I have tried hidden form fields, but it isn’t showing in the post, or I do not know how to grab it…
Controller:

public ActionResult AddCar(int id)
{
ViewBag.Id = id;
return View();
}

View (tried):

    @using (Html.BeginForm("AddReturn", "DealerAdmin", new { id = carId }))
    {
View (tried):
     @Html.Hidden(carId.ToString())

HOw do I retrieve the value in my post action in my controller? Or is there a better/different way to approach it?
THanks

Answer 1

The hidden field should works. The problem is that your controller did not accept it.

You can use ViewModel to achieve this. Or, use the code below in your action:

id = Request.Form["id"]
