Asp.net mvc razor render partial view using ajax helper

This is the extension to my blog in which I demonstrated rendering of the partial view using jquery Ajax . I want to demonstrate here yet another way by which partial view can be rendered without page refresh. Here is the implementation.

Step 1:

I will again be using DisplayData class in my demo. Here is it.

  
    public class DisplayData
    {
       public int ID { get; set; }
       public DisplayData(int ID)
       {
              this.ID = ID;
       }
    }

Step 2:

Create a PartialDemo page

@model IEnumerable<MvcApplication5.Models.DisplayData>
@{
    ViewBag.Title = "PartialDemo";
}


@Ajax.ActionLink("Click 1", "PartialDemo", "PartialDemo", new {Data= "1" }, new AjaxOptions { UpdateTargetId = "rsvpmsg" })
@Ajax.ActionLink("Click 2", "PartialDemo", "PartialDemo", new {Data= "2" }, new  AjaxOptions { UpdateTargetId = "rsvpmsg" })

<div id="rsvpmsg">
@{ Html.RenderPartial("PartialDemoUC", this.Model);}
</div>

Step 3:

Create a User Control PartialDemoUC.cshtml

@model IEnumerable<dynamic>

@foreach(var items in Model)
{
   @items.ID    
}

Step 4:

In a PartialDemo controller create an Action method for rendering the partial view on the first call to the method and then on an ajax call(on the click of the link)

  
    public ActionResult PartialDemo(string Data)
    {
       List<DisplayData> Display = new List<DisplayData>();

       if (Request.IsAjaxRequest())
       {
          if (Data == "1")
          {
             Display.Add(new DisplayData(3));
             Display.Add(new DisplayData(4));
          }
          else
          {
            Display.Add(new DisplayData(5));
            Display.Add(new DisplayData(6));
          }
          return PartialView("PartialDemoUC",Display);
       }
       else
       {
           Display.Add(new DisplayData(1));
           Display.Add(new DisplayData(2));
           return View("PartialDemo", Display);
       }
    }
