MVC - 如何将模型从视图传递到控制器

Question

我正在使用一个模型,需要流经一系列控制器和视图,一路上操作它(只在第一个控制器上加载它).有没有办法将模型从视图中持久保存到控制器等等？

这是我的代码.

模型:

    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; }
    }

}

填充模型并将其发送到视图后,将使用模型显示所有内容.我认为在表单标签上坚持这样的模型:

<% using (Html.BeginForm("Items", "ROW", Model))

这是ROW控制器的post Items Action:

    [ActionName("Items"), AcceptVerbs(HttpVerbs.Post)]
    public ActionResult Items(ROWModel model, FormCollection collection)

问题是Model没有返回我最初填充它的TBLRETURNABLEITEMS列表.它保留了我填充的其他属性,但不保留列表.如何维护此模型的数据,而不必在每个控制器上重新加载它.

我认为你可以使用TempData.

所以像这样:

    [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);
    }
