如果无论如何我碰巧有
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View
我有一个普通的表单来填充模型属性,但List<DoorDesignModel>
我正在使用用户控件并使用
<%Html.RenderPartial("DoorDesign", Model.Doors); %>
在DoorDesign.ascx
里面我有:
<%@ Control
Language="C#" AutoEventWireup="true"
Inherits="System.Web.Mvc.ViewUserControl<List<MyProject.Backend.Models.DoorDesignModel>>" %>
显示所有表单我有for
子句
MyProject.Backend.Models.DoorDesignModel field;
for (i = 0; i < Model.Count; i++) {
field = Model[i];
...
}
我正在使用HTML
<input type="file" value="Upload file"
name="Doors.FrontFile[<%: i %>]" id="Doors.FrontFile[<%: i %>]">
但很快我按下提交按钮,我的模型返回null
列表:(
我在启动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);
}
为了从RenderPartial
部分返回门列表,我需要具备哪些内容?
View的简单模型
答案 0 :(得分:1)
刚遇到同样的问题。找到这个网站:http://weblogs.asp.net/nmarun/archive/2010/03/13/asp-net-mvc-2-model-binding-for-a-collection.aspx
基本上就是这一切
<input type="file" value="Upload file" name="Doors[<%: i %>].FrontFile" id="Doors[<%: i %>].FrontFile">
