如何处理`PartialRender`模型？ [英] How to handle `PartialRender` Models?

问题描述

如果以任何方式我碰巧有

if by any means I happen to have

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; }
}

在我的查看我有一个正常的形式来填充模型属性，但列表＆LT; D​​oorDesignModel＆GT; 我M使用的用户控制和使用

and in my View I have a normal form to populate the Model Properties but the List<DoorDesignModel> I'm using a User Control and use

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

在 DoorDesign.ascx 我有：

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

显示所有表格我有一个为条款

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

和我使用HTML

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

但很快我preSS提交按钮，我的模型返回空列表:(
而我创建和设置启动查看时，一个新的列表

but soon I press the submit button, my model returns a null List :( and I'm creating and setting a new list when starting the View as

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);
}

什么我需要有为了从的RenderPartial 部分返回门列表？

推荐答案

刚刚有同样的问题。发现这个网站：<一href=\"http://weblogs.asp.net/nmarun/archive/2010/03/13/asp-net-mvc-2-model-binding-for-a-collection.aspx\" rel=\"nofollow\">http://weblogs.asp.net/nmarun/archive/2010/03/13/asp-net-mvc-2-model-binding-for-a-collection.aspx

Just had the same problem. Found this website: http://weblogs.asp.net/nmarun/archive/2010/03/13/asp-net-mvc-2-model-binding-for-a-collection.aspx

从本质上讲它是所有关于
＆LT;输入类型=文件VALUE =上传文件NAME =门[＆LT;％：I％]的计算值FrontFile。ID =门[＆LT;％：I％＆GT; ] .FrontFile＆GT;

Essentially it is all about <input type="file" value="Upload file" name="Doors[<%: i %>].FrontFile" id="Doors[<%: i %>].FrontFile">
