パーシャルビューから親ビューへの一時データの送信方法

Question

パーシャルビューから親ビューへの一時データの送信方法？私はデータベースへの保存成功に関する情報が必要です。 TempDataまたはHttpContext.Itemsを例にしてください。問題は

これはMVCに

@model AplikacjaHelpDesk.ViewModels.ListOrdersUserViewModel 
@using AplikacjaHelpDesk.Infrastructure 
@{ 
    ViewBag.Title = "List Orders Users"; 
    Layout = "~/Views/Shared/_LayoutAdministracja.cshtml"; 
} 

<div class="container-fluid"> 
    <img src="~/Content/Images/Layout/Home.png" /> 
    <a href="link"> 
     @Html.MvcSiteMap().SiteMapPath() 
    </a> 
    <h2><span class="glyphicon glyphicon-user"></span>&nbsp<strong>List Orders </strong></h2> 
    <br /><br /> 
    <div id="divLoading" class="panel panel-primary text-center text-primary" style="display:none;"> 
     <h3><strong>Please wait for post!</strong></h3> 
    </div> 
    <div id="divLoadingForm" class="panel panel-primary text-center text-primary" style="display:none;"> 
     <h3><strong>Please wait for form</strong></h3> 
    </div> 
    @if (ViewBag.Information != null) 
      { 
     <div class="alert alert-warning"><h4><strong>@TempData["Add-Post"]</strong></h4></div> 
    }*@ 

    <table class="table table-responsive table-striped" style="text-combine-upright:all;"> 
     <tr style="text-transform: uppercase; text-combine-upright:all;"> 
      <th> 
       <label>Numer Order</label> 
      </th> 
      <th> 
       <label>Acceptance Date</label> 
      </th> 
      <th> 
       <label>Date of planned completion of the order</label> 
      </th> 
      <th> 
       <label>Data finish</label> 
      </th> 
      <th style="width: 160px;"></th> 
      <th style="width: 160px;"></th> 
     </tr> 

     @foreach (var item in Model.ListOrdersUser) 
     { 

      <tr class="panel panel-primary"> 
       <td> 
        <h5><strong>Nuber Orders: @Html.DisplayFor(modeItem => item.IdOrder)</strong></h5> 
       </td> 
       <td> 
        @Html.DisplayFor(modelItem => item.DateAccept) 
       </td> 
       <td> 
        @Html.DisplayFor(modelItem => item.DataPlaningFinish) 
       </td> 
       <td> 
        @Html.DisplayFor(modelItem => item.DataFinish) 
       </td> 
       <td> 
        @Ajax.ActionLink("Show Post Order", "_ListPost", new { idOrder = @item.IdOrder }, new AjaxOptions() 
       { 
        HttpMethod = "GET", 
        LoadingElementId = "divLoading", 
        UpdateTargetId = "divPosition", 
        InsertionMode = InsertionMode.Replace 

       }, new { @class = "btn btn-primary" }) 
       </td> 
       <td> 


        @Ajax.ActionLink("Add Answer", "_AddPost", new { idZlecenia = @item.IdZlecenia }, new AjaxOptions() 
       { 
        HttpMethod = "GET", 
        LoadingElementId = "divLoadingForm", 
        UpdateTargetId = "divAddPozycje", 
        InsertionMode = InsertionMode.Replace 

       }, new { @class = "btn btn-primary" }) 
       </td> 

      </tr> 
      ... 
      <tr id="divAddPozycje"></tr> 
     } 
    </table> 

</div> 

とコントローラ

[HttpPost] 
     [ValidateAntiForgeryToken] 
     public PartialViewResult _AddPost(int idOrder, AddPositionViewModel viewModel) 
     { 
      var findOrder = db.Order.Find(idOrder); 

      if (ModelState.IsValid) 
      { 

       OrderPosition position = new OrderPosition { Description = viewModel.Description }; 
       db.OrderPosition.Add(position); 
       //db.Entry(position).State = System.Data.Entity.EntityState.Unchanged; 
       findOrder.OrderPositionList.Add(position); 
       db.SaveChanges(); 
       ViewBag.Information = position;     

       if (ViewBag.Information != null) 
       { 
        TempData["Add-Post"] = string.Format("Odpowiedz użytkownika {0} została dodana!", User.Identity.Name); 
        //HttpContext.Items["Info"] = string.Format("Odpowiedz użytkownika {0} została dodana!", User.Identity.Name); 
       } 

      } 
      Thread.Sleep(2000); 
      return PartialView(); 

     } 

//Method Parent View 

public ActionResult ListOrder(int? IdStatusOrder) 
     { 
      var ListAllOrder = db.Order.ToList(); 
      var userId = User.Identity.GetUserId(); 
      var viewodel = new ListOrdersUserViewModel() 
      {   
       ListOrdersUser = ListOrders 
      }; 
       }; 
      return View(viewodel); 
     } 

、ビュー内のメソッドである（親ビューに一部のビューから）差分表示の間保存の成功に関する情報を送信する方法であります部分ビュー - フォーム

    ViewBag.Title = "Add Post"; 
    Layout = null;

Answer 1

TempData値を返します_AddPostのGETバージョン実装します

[HttpGet] 
[ValidateAntiForgeryToken] 
public JsonResult _AddPost() 
{ 
    return Json(TempData["Add-Post"]); 
} 

があなたの元ActionLinkを変更し、OnComplete機能を追加します。

@Ajax.ActionLink("Add Answer", "_AddPost", new { idZlecenia = @item.IdZlecenia }, new AjaxOptions() 
{ 
    HttpMethod = "POST", // Not "GET" 
    LoadingElementId = "divLoadingForm", 
    UpdateTargetId = "divAddPozycje", 
    InsertionMode = InsertionMode.Replace, 
    OnComplete = "updateMyAlert();" // Add this 

}, new { @class = "btn btn-primary" }) 

はmy-alert-text要素を更新し、新たなActionLinkでそれをフォローします：

@Ajax.ActionLink("", "_AddPost", new {}, new AjaxOptions() 
{ 
    HttpMethod = "GET", 
    UpdateTargetId = "my-alert-text", 
    InsertionMode = InsertionMode.Replace, 
    OnSuccess = "showMyAlertIfNeeded();" 

}, new { id = "update-my-alert-action-link" }) 

は、関連するHTMLとJavaScriptで上記を補完

：

<div class="alert alert-warning" id="my-alert" style="display: none;"> 
    <h4><strong id="my-alert-text"></strong></h4> 
</div> 
<script> 
    function updateMyAlert() { 
     document.getElementById("update-my-alert-action-link").click(); 
    } 
    function showMyAlertIfNeeded() { 
     var display = document.getElementById("my-alert-text").text ? "" : "none"; 
     document.getElementById("my-alert").style.display = display; 
    } 
</script>
