返回默認值

一些奇怪的MVC模型性質正在發生的事情，我無法理解爲什麼..這裏的情景 -返回默認值

我有幾個屬性的模型，當我填充模型在模型的屬性確實有值設置（通過放置斷點進行檢查）。它也出現在視圖中，但不會顯示在文本框中。它顯示了默認值（通過查看頁面上的項目文本框，因爲它具有0而猜測）。

下面是我的模型 -

public class PriceEnquiryModel 
{ 
    [DisplayName("Item")] 
    public int item { get; set; } 

    [DisplayName("Description")] 
    public string description { get; set; } 

    [DisplayName("UOP")] 
    public string uop { get; set; } 

    [DisplayName("UOS")] 
    public string uos { get; set; } 

    [DisplayName("Pack Description")] 
    public string pack_description { get; set; } 

    [DisplayName("Pack Size")] 
    public string PackSize { get; set; } 
}

這是控制器的代碼爲 -

public ActionResult Search(PriceEnquiryModel price) 
{ 
    var priceEnquiryModel = new PriceEnquiryModel(); 

    // Read parameter values from form. 
    int item = Convert.ToInt32(Request.Form["txtSearch"].ToString()); 
    int maxrow = Convert.ToInt32(Request.Form["txtmaxrow"].ToString()); 
    string priceType = !string.IsNullOrWhiteSpace(price.priceType) && price.priceType.ToUpper().Equals("STA") ? "N" : "Y"; 

    // Get the price information 
    var operationResult = priceBal.SearchPriceEnquiry(0, item, price.price_scheme, priceType, maxrow);    
    var priceEnquiryDomList = (List<PriceEnquiryDom>)operationResult[0].Result; 

    // Check if we have something 
    if (priceEnquiryDomList != null && priceEnquiryDomList.Count > 0) 
    { 
     // Parse the model. 
     priceEnquiryModel = helper.ConvertDomToModel(priceEnquiryDomList[0]); 
     // Prepare the list. 
     priceEnquiryModel.PriceEnquiryModelList = new List<PriceEnquiryModel>(); 
     foreach (var priceEnquiryDom in priceEnquiryDomList) 
     { 
      var priceEnquiryModelListItem = helper.ConvertDomToModel(priceEnquiryDom); 
      priceEnquiryModel.PriceEnquiryModelList.Add(priceEnquiryModelListItem); 
     } 
     Session["mainModel"] = priceEnquiryModel; 
    } 

    // Prepare product drop down list items if searched by product desc 
    if (TempData.Count > 0 && TempData["Products"] != null) 
    { 
     var products = TempData["Products"] as List<ProductSearchByDescModel>; 
     ViewBag.Products = products; 
    } 
    return View("Index", priceEnquiryModel); 
}

這是在視圖模型（在調試） -
