Question

渲染ChildAction时遇到问题：

 [ChildActionOnly]
    public ActionResult ListAll()
    {

        var user_id = (int)Membership.GetUser().ProviderUserKey;
        var client_id = from d in db.Connexions 
                        where d.userId == user_id && d.Action == "Creation"
                        select d.ClientID;
        //var cust_id = (int)client_id;

        var lastClient = from d in db.Clients
                         where d.ClientID == client_id.Max()
                         select d;
        return View(lastClient);
     }

我在创建页面中将其呈现在这里：

  <div class="editor-label">
        @Html.LabelFor(model => model.dateOut)
    </div>
    <div class="editor-field">
        @Html.EditorFor(model => model.dateOut)
        @Html.ValidationMessageFor(model => model.dateOut)
    </div>
    <p> @{Html.RenderAction("ListAll");} </p> //---- Here

我不知道为什么HttpException会出现详细错误：执行处理程序的子请求时出错＆＃39; System.Web.Mvc.HttpHandlerUtil + ServerExecuteHttpHandlerAsyncWrapper＆＃39;。

这是我的ListAll局部视图，并使用客户端模型进行强类型化：

@model Gestion_restrictions.Models.Client

    <th>
        @Html.DisplayNameFor(model => model.portfolio)
    </th>
    <th>
        @Html.DisplayNameFor(model => model.dateIn)
    </th>
   <td>
        @Html.DisplayFor(modelItem => item.portfolio)
    </td>

等...

有人能帮助我吗？

谢谢

视图的模型定义为Client，但您传递的是IEnumerable<Client>。更改以下

var lastClient = from d in db.Clients
  where d.ClientID == client_id.Max()
  select d;

到

var lastClient = (from d in db.Clients
  where d.ClientID == client_id.Max()
  select d).FirstOrDefault(); // or .SingleOrDefault()
return View(lastClient);

将childAction渲染到父视图asp.net mvc时出现问题
