如何處理`PartialRender`模型？

如果我碰巧有如何處理`PartialRender`模型？

public class DoorsModel 
{ 
    public DoorsModel() { } 

    public HttpPostedFileBase Image { get; set; } 
    public String DoorLayout { get; set; } 
    public bool ReplicateSettings { get; set; } 
    public List<DoorDesignModel> Doors { get; set; } 
} 

public class DoorDesignModel 
{ 
    public DoorDesignModel() { } 

    public HttpPostedFileBase FrontFile { get; set; } 
    public HttpPostedFileBase BorderFile { get; set; } 
}

任何手段，在我View我有一個正常的形式來填充模型屬性，但List<DoorDesignModel>我使用的是用戶控制和使用

<%Html.RenderPartial("DoorDesign", Model.Doors); %>

裏面DoorDesign.ascx我：

<%@ Control 
     Language="C#" AutoEventWireup="true" 
     Inherits="System.Web.Mvc.ViewUserControl<List<MyProject.Backend.Models.DoorDesignModel>>" %>

顯示所有形式我有一個for條款

MyProject.Backend.Models.DoorDesignModel field; 
for (i = 0; i < Model.Count; i++) { 
    field = Model[i]; 
    ... 
}

和我使用的HTML

<input type="file" value="Upload file" 
    name="Doors.FrontFile[<%: i %>]" id="Doors.FrontFile[<%: i %>]">

但很快我按下提交按鈕，我的模型返回null列表:( ，我創建和設置一個新的列表開始查看

public ActionResult Doors() 
{ 
    DoorsModel model = new DoorsModel(); 

    model.Doors = new List<DoorDesignModel>(); 
    for (int i= 1; i<= 24; i++) // Add 24 Doors 
     model.Doors.Add(new DoorDesignModel()); 

    return View(model); 
} 

[HttpPost] 
public ActionResult Doors(DoorsModel model) 
{ 
    // model.Doors is always null !!! 

    if (ModelState.IsValid) 
     ViewData["General-post"] = "Valid"; 
    else 
     ViewData["General-post"] = "NOT Valid"; 

    return View(model); 
}

什麼時候我必須爲了從RenderPartial部分歸還門列表？
