問題與Html.RenderPartial -MVC

我想更新我的網頁中的一個小區域。我只是想重新加載ascx頁面（不刷新整個頁面）當用戶單擊按鈕。代碼示例如下所示。裝載工作正常。問題與Html.RenderPartial -MVC

但是，在ajax請求它沒有顯示加載的數據（意味着名稱和地址已更改）。我可以看到在調試新的數據的html正在爲ajax requset之後的ascx頁面構建。但它沒有更新視圖。

VIEW

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> 
<script type="text/javascript" src="../../Scripts/MicrosoftAjax.js"></script> 
<script src="../../Scripts/MicrosoftMvcAjax.js" type="text/javascript"></script> 

<% using (Ajax.BeginForm("Index", "Home", 
         new AjaxOptions { 

          HttpMethod="GET", 

          })) 

    { %><button type="submit" name="test">test button</button> 

    <% } %> 
     <% Html.RenderPartial("test"); %>  
</asp:Content>

控制器

public ActionResult Index() 
    { 
     Models.HomeModels obj = new Models.HomeModels(); 
     obj.name = "initial name"; 
     obj.address = "initial address";   
     if (Request.IsAjaxRequest()) 
     { 
      obj.name="test"; 
      obj.address = "success"; 
      return PartialView("test",obj); 
     } 
     return View(obj); 
    }

Test.ascx

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<test_partial_renderning.Models.HomeModels>" %> 
<% if(Model.address!=null) 
{ %> 
    <%= Html.Encode(Model.name) %><br /> 
    <%= Html.Encode(Model.address) %><br /> 
<% } %>

型號

public string name { get; set; } 
    public string address { get; set; }

您必須指定 'UpdateTargetId'（HTML目標進行更新）。嘗試以下操作。

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> 
<script type="text/javascript" src="../../Scripts/MicrosoftAjax.js"></script> 
<script src="../../Scripts/MicrosoftMvcAjax.js" type="text/javascript"></script> 

<% using (Ajax.BeginForm("Index", "Home", 
         new AjaxOptions { 

          HttpMethod="GET", 
          UpdateTargetId = "result" 

          })) 

    { %><button type="submit" name="test">test button</button> 

    <% } %> 
     <div id="result"> 
     <% Html.RenderPartial("test"); %>  
     </div> 
</asp:Content>
