MVC 4 ActionResult未被第二次擊中

我們有一個顯示數據行的索引頁面。當我們去編輯一行時，Edit ActionResult會被點擊並顯示數據供我們編輯。然後當我們去提交更改時，HttpPost ActionResult被命中並且數據被保存。MVC 4 ActionResult未被第二次擊中

我們可以返回到索引頁面並查看已保存的更改，但是如果我們再次嘗試編輯數據，則不會觸發Edit ActionResult，並且會顯示舊數據，直到我們點擊F5，然後觸發編輯ActionResult並刷新dat。

我們如何確保Edit ActionResult每次被擊中而不必進行硬刷新？

謝謝！

這裏的控制器上編輯的ActionResult：

[CustomAuthorizePDG] 
    public ActionResult Edit(int id = 0) 
    { 
     var model = this._db.ProductApprovals_ProductApproval.Find(id); 
     if (model == null) { 
      return HttpNotFound(); 
     } 
     var spServer = ConfigurationManager.ConnectionStrings["SPServer"].ConnectionString; 
     ViewBag.ProductStatusId = new SelectList(this._db.ProductApprovals_ProductStatus, "ProductStatusId", "ProductStatus", model.ProductStatusId); 
     return View(model); 
    }

然後HttpPost AtionResult：

[CustomAuthorizePDG] 
    [HttpPost] 
    [ValidateAntiForgeryToken] 
    [ErrorHandler] 
    public ActionResult Edit(ProductApprovals_ProductApproval model, HttpPostedFileBase file) 
    { 
     if (ModelState.IsValid) { 
       if (file != null && file.ContentLength > 0) { 
        var sp = new ProductApprovalDataContext(new Uri("http://sp-appcentral-int/ProductApproval/_vti_bin/ListData.svc")) 
        { 
         Credentials = CredentialCache.DefaultNetworkCredentials 
        }; 

        var productApprovalForm = sp.ProductApprovalForm.Where(x => x.ProductApprovalId == model.ProductApprovalId.ToString(CultureInfo.InvariantCulture)).FirstOrDefault(); 

        if (productApprovalForm != null) { 
         var fileName = Path.GetFileName(file.FileName); 
         var extension = Path.GetExtension(file.FileName); 
         var name = string.Format("{0}{1}", model.ProductApprovalId, extension); 
         var path = string.Format("/ProductApproval/Product Approval Form/{0}", name); 
         var contentType = extension == "docx" ? "application/vnd.openxmlformats-officedocument.wordprocessingml.document" : "application/msword"; 

         productApprovalForm.CheckedOutTo = new UserInformationListItem 
         { 
          UserName = User.Identity.Name 
         }; 
         productApprovalForm.Title = fileName; 
         sp.SetSaveStream(productApprovalForm, file.InputStream, false, contentType, path); 
         sp.SaveChanges(SaveChangesOptions.ReplaceOnUpdate); 

         this.UpdateProductApprovalWithDocument(model, path, fileName); 
        } 
       } 

       this._db.Entry(model).State = EntityState.Modified; 
       this._db.SaveChanges(); 

      return RedirectToAction("Index"); 
     } 

     ViewBag.ProductStatusId = new SelectList(this._db.ProductApprovals_ProductStatus, "ProductStatusId", "ProductStatus", model.ProductStatusId); 

     return View(model); 
    }

所以，當HttpPost編輯被解僱它成功地保存更改和它們在顯示索引視圖。如果您然後返回到Edit ActionResult，則會顯示初始值，直到執行刷新。我們在代碼上放置了一個斷點，第二次編輯ActionResult並沒有被觸發，直到你點擊F5 ...

你的代碼在哪裏？我認爲沒有代碼，沒有人可以幫助你... – MRB
