我如何从业务逻辑中刷新局部视图 [英] how I refresh the partial view from Business logic

问题描述

查看：索引

 @ {
 ViewBag.Title =主页; 
} 
 
 @section Content1 
 {
 <   div  >  
 @ Ajax.ActionLink（Just refresh，_ Test，Home，null，new AjaxOptions（） {UpdateTargetId =ContentRefresh，HttpMethod =Post}，null）
 <   / div  >  
 
 @ Html.Partial（_ Test）
} 
 
 @section Content2 
 {
 <   div     id   =  ContentRefresh >  
 @ Html.Partial（_ Test2）
 <   / div  >  
} 

查看：_Test

 @ using（Ajax.BeginForm （_ Test，Home，null，new AjaxOptions（）{UpdateTargetId =ContentRefresh，HttpMethod =Post}，null））
 {
 @ Html.TextBox（Name） ; 
 <  输入   < span class =code-attribute> type   =  submit    value   = 发送名称    /  >  
} 

查看：_Test2

 @ ViewBag.Name：@ ViewBag.DateTime 

控制器：

  public  ActionResult _Test（FormCollection表单）
 {
  string  name = form [< span class =code-string> 名称]; 
 
  if （Request.IsAjaxRequest（））
 {
 Thread thread =  new  Thread（（）= >  RunThread（））; 
 thread.Start（）; 
 
 ViewBag.Name = name ==  null ？  没有人，只需刷新：name; 
 ViewBag.DateTime = DateTime.Now.ToShortTimeString（）; 
 
  return  PartialView（  _Test2\" ）; 
} 
 其他 
 {
 返回查看（ ）; 
} 
} 

此事件是来自业务逻辑的调用。

< pre lang =cs> public void ChangeEventFromBusinessLogic（ object o）来自RunThread的
{
// 事件....
// 刷新我的观点
}

来自视图的ajax调用确实有效。如何在没有任何用户操作的情况下从业务逻辑刷新视图。



我是怎么做到的？

View: Index

@{
    ViewBag.Title = "Home Page"; 
}

@section Content1
{ 
    <div>  
     @Ajax.ActionLink("Just refresh", "_Test", "Home", null, new AjaxOptions() { UpdateTargetId = "ContentRefresh", HttpMethod = "Post" }, null) 
    </div>

    @Html.Partial("_Test")
}
    
@section Content2
{ 
    <div id="ContentRefresh">
       @Html.Partial("_Test2")
    </div>
}

View: _Test

@using (Ajax.BeginForm("_Test", "Home", null, new AjaxOptions(){UpdateTargetId = "ContentRefresh", HttpMethod = "Post" }, null))
    {  
        @Html.TextBox("Name"); 
        <input type="submit" value="Send name" /> 
    }

View: _Test2

@ViewBag.Name:  @ViewBag.DateTime 

Controller:

public ActionResult _Test(FormCollection form)
{
    string name = form["Name"];

    if (Request.IsAjaxRequest())
    {
         Thread thread = new Thread(() => RunThread());
         thread.Start();

        ViewBag.Name = name == null ? "No one, just refreshing" : name;
        ViewBag.DateTime = DateTime.Now.ToShortTimeString();

        return PartialView("_Test2");
    }
    else
    {
        return View();
    }
}

This event is call from business logic.

public void ChangeEventFromBusinessLogic(object o)
{
      //event from RunThread....
      //refresch my view
}

the ajax call from the view does work. how I refresh the view from Business logic without any user action.

how I do this?
