Model Binder in ASP.Net MVC 3 is not working_问答_开发者

I am having a problem to bind the data sent with the model. What I would like to bind is the OrderStatus that even if I pass it 10 it is always turned into 0. I don't know why. I made this part bold to make it easier to detect in code:

Data sent as JSON:

 {"CustomerOrderHeader":{"OrderNumber":"5",
    "PartnerName":"BLI",
    "Reference":"",
    "ShippingDate":"10/152011",
    "OrderStatusName":"Approved",
    "CustomerOrderHeader.OrderStatus":"10",
    "TotalAmount":"16.00",
    "CustomerOrderHeader.CurrencyId":"0",
    "CustomerOrderHeader.LanguageId":"0",
    "DaLine1":"",
    "DaLine2":"",
    "DaCity":"",
    "DaPostalCode":"",
    "DaState":"",
    "DaCountry":"",
    "BaLine1":"",
    "BaLine2":"",
    "BaCity":"",
    "BaPostalCode":"",
    "BaState":"",
    "BaCountry":"",
    "Notes":""},
    "CustomerOrderLines":[{"Id":214,"Num":10,"PartNumber":"dasdasd","Description":"dadadasd","OrderedQty":4,"UoM":"inteee","SalesPrice":null,"Amount":16,"LineStatus":10,"ConfirmedShippingDate":null,"ReservedQty":0,"DeliveredQty":0,"RemainingQty":4}]}

The method signature:

 [HttpPost]
 public JsonResult SaveOrUpdateOrderLines( CustomerOrderModel customerOrderModel )

and the model:

public class CustomerOrderModel
{
    public CustomerOrderModel()
    {
        this.CustomerOrderLines = new List<CustomerOrderLineModel>();
        this.CustomerOrderHeader = new CustomerOrderHeaderModel();
    }

    public CustomerOrderHeaderModel CustomerOrderHeader
    { get; set; }

    public List<CustomerOrderLineModel> CustomerOrderLines
    { get; set; }

}

Customer Order List Model:

   public class CustomerOrderLineModel
    {
        public CustomerOrderLineModel()

        }

        public String LineStatus { get; set; }


        private int? _lineStatusNum;

                _lineStatusNum = null;
                return null;
            }
            set
            {
                if (value == 0)

                {
                   _lineStatusNum  = value;
                    this.LineStatus = "Draft";
                }
                if (value == 10)
                {
                    _lineStatusNum = value;
                    this.LineStatus = "Approved";

At first glance the problem I see is that you are sending "OrderStatusName", but that property only has a get function and not a set.

I haven't examined the rest of the code or tested this; but if you don't have a SET for OrderStatusName, it won't work.

You could either send in the OrderStates (which has both get; set;), or implement the set to the OrderStatusName, which I wouldn't recommend as is not good practice.

Hope this helps, -covo
