MVC驗證沒有解僱

我正在使用ASP.NET MVC 2.我的表單驗證沒有解僱。我無法弄清楚這裏有什麼問題。MVC驗證沒有解僱

型號：

public class Stock 
    { 
     public int StockID { get; set; } 

     [Required(ErrorMessage = "Please Select a Client")] 
     public int ClientID { get; set; } 

     [Required(ErrorMessage = "Please Select An Item")] 
     public int ItemID { get; set; } 


      [Required(ErrorMessage = "Please Enter Item Count")] 
      public int ItemCount { get; set; } 

      [Required(ErrorMessage = "Please Enter Item Price")] 
     public double Price { get; set; } 

      [Required(ErrorMessage = "Please Enter Other Expences")] 
     public double OtherExpences { get; set; } 

     public double TotalStockValue { get; set; } 

      [Required(ErrorMessage = "Please Enter Delivery date")] 
     public DateTime DeliveryDate { get; set; } 

     public string Description { get; set; } 
     public List<Client> lstClient { get; set; } 
     public IEnumerable<Item> lstItem { get; set; } 

     public string ClientName { get; set; } 
     public string ItemName { get; set; } 
    }

控制器：

[HttpPost] 
     public ActionResult Create(FormCollection collection) 
     { 

       try 
       { 
        if (ModelState.IsValid) 
        { 
         StockRepository rep = new StockRepository(); 
         Stock stock = new Stock(); 
         stock.ClientID =Convert.ToInt32(Request.Form["ClientID"]); 
         stock.DeliveryDate =Convert.ToDateTime(Request.Form["DeliveryDate"]); 
         stock.Description = Request.Form["Description"]; 
         stock.ItemCount =Convert.ToInt32(Request.Form["ItemCount"]); 
         stock.ItemID =Convert.ToInt32(Request.Form["ItemID"]); 
         stock.Price =Convert.ToDouble(Request.Form["Price"]); 
         stock.OtherExpences = Convert.ToDouble(Request.Form["OtherExpences"]); 
         stock.TotalStockValue =Convert.ToDouble((stock.Price * stock.ItemCount)+stock.OtherExpences); 
         rep.Create(stock); 
         rep.Save(); 
         return RedirectToAction("Index"); 
        } 
        else 
         return View(); 
       } 
       catch 
       { 
        return View(); 
       } 

     }

前最後我得到了服務器端驗證工作。添加對UpdateModel或TryUpdateModel的調用，該調用將填充模型並啓動正確設置ModelState.IsValid屬性的驗證規則。

[HttpPost] 
     public ActionResult Create(FormCollection collection) 
     { 

       try 
       { 
        Stock stock = new Stock(); 
        TryUpdateModel(stock); 

        if (ModelState.IsValid) 
        { 
         StockRepository rep = new StockRepository(); 

         stock.ClientID =Convert.ToInt32(Request.Form["ClientID"]); 
         stock.DeliveryDate =Convert.ToDateTime(Request.Form["DeliveryDate"]); 
         stock.Description = Request.Form["Description"]; 
         stock.ItemCount =Convert.ToInt32(Request.Form["ItemCount"]); 
         stock.ItemID =Convert.ToInt32(Request.Form["ItemID"]); 
         stock.Price =Convert.ToDouble(Request.Form["Price"]); 
         stock.OtherExpences = Convert.ToDouble(Request.Form["OtherExpences"]); 
         stock.TotalStockValue =Convert.ToDouble((stock.Price * stock.ItemCount)+stock.OtherExpences); 
         rep.Create(stock); 
         rep.Save(); 
         return RedirectToAction("Index"); 
        } 
        else 
         return View(); 
       } 
       catch 
       { 
        return View(); 
       } 

     }

如果你的行動接受一個模型對象作爲參數的內置了對MVC 2服務器端驗證才起作用。這會導致MVC創建模型對象並自動將傳入的表單輸入值映射到它。作爲此過程的一部分，它還將檢查模型的DataAnnotation驗證屬性是否有效。如果一切都有效，那麼我們代碼中的ModelState.IsValid檢查將返回true。

當你的行動接受的FormCollection這並不因此發生，DataAnnotation驗證屬性永遠不會評估和ModelState.IsValid永遠不會設置。我們可以自己簡單地執行這些步驟來糾正這個問題。 MVC 2提供了我們可以用來執行此操作的函數（UpdateModel和TryUpdateModel）。區別在於，如果存在驗證錯誤，Update將拋出，而TryUpdate將簡單地將IsValid設置爲false。

使用的UpdateModel的好處是，空模型將與形式集合大家的值來填充。

你應該已經建立ClientValidationEnabled爲真正在網絡配置或添加以下代碼使用BeginForm

<% Html.ClientValidationEnabled = true; %>

得到一個錯誤「不包含定義ClientValidationEnabled」 – chamara 2013-05-04 07:15:19

那說明你還沒有包含在你的項目中MicrosoftMvcJqueryValidation。請參閱http://blogs.msdn.com/b/rickandy/archive/2009/10/03/client-side-validation-for-mvc-2-p2.aspx上的最佳可能場景 – DeveloperBuddy 2013-05-04 07:23:51
