MVC - How to pass model from view to controller

asp.net-mvc, model-view-controller

Solution

I think that you can use TempData for that.

So something like this:

    [AcceptVerbs(HttpVerbs.Get)]
    public ActionResult TestA()
    {
        MyModel model = new MyModel();
        model.Something = "Test";
        return View(model);
    }

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult TestA(MyModel model)
    {
        TempData["MyModel"] = model;
        return RedirectToAction("TestB");
    }

    [AcceptVerbs(HttpVerbs.Get)]
    public ActionResult TestB()
    {
        MyModel myModel = (MyModel)TempData["MyModel"];
        return View(myModel);
    }

Problem

I am working with a model that needs to flow through a series of controllers and views manipulating it along the way(Only loading it on the first controller). Is there a way to persist the model from the view back down to a controller and so forth? Here is my code. Model: ``` public class ROWModel { #region Properties //Request public List<TBLRETURNABLEITEMS> TBLRETURNABLEITEMS { get; set; } //public List<ReturnReasons> ReturnReasons { get; set; } public int Order_No { get; set; } public string First_Name {get; set; } public string Last_Name {get; set; } public string Company { get; set; } public string Address_1 { get; set; } public string Address_2 { get; set; } public string City { get; set; } public string State { get; set; } public string Postal_Code { get; set; } public string Email { get; set; } public string Phone { get; set; } public string CustomerCode {get; set; } public string TerritoryCode {get; set; } //Post #endregion #region Constructor public ROWModel() { } #endregion } public class ReturnableItems : IComparable<ReturnableItems> { private int _id; private decimal _ordered; private decimal _shipped; public int Id { get { return _id; } set { _id = value; } } public decimal Ordered { get { return _ordered; } set { _ordered = value; } } public decimal Shipped { get { return _shipped; } set { _shipped = value; } } ``` } After populating the model and sending it to the view everything is displayed using the model as it should be. I think stick the model like so on the form tag: ``` <% using (Html.BeginForm("Items", "ROW", Model)) ``` Here is the post Items Action of the ROW controller: ``` [ActionName("Items"), AcceptVerbs(HttpVerbs.Post)] public ActionResult Items(ROWModel model, FormCollection collection) ``` Problem is Model doesn't return the list of TBLRETURNABLEITEMS i populated it with initially. It keeps the other properties i populated but not the list. How do i maintain this model's data without having to reload it on every controller should i want to.
