foreach所在ASP.Net MVC IEnumerable的财产和CheckBoxFor

问题描述

我认为这个问题适用于任何的为HTML辅助，但我的具体问题是使用CheckBoxFor ...

I believe this question applies to any of the "For" Html helpers, but my specific problem is using CheckBoxFor...

我有一个模型，它是IEnumerable类型，其中的权利是一个简单的POCO。这种模式实际上是我创建了一个EditorTemplate一个更大的模型的属性。这里是我的模型的大局观：

I have a model that is of type IEnumerable, where rights is a simple POCO. This model is actually a property of a bigger model that I created an EditorTemplate for. Here is the bigger picture of my model:

public class bigmodel
{
     public string Title {get; set;}
     public string Description {get; set;}

     [UIHint("ListRights")]
     public IEnumerable<rights> Rights {get;set;}
}

public class rights
{
    public bool HasAccess {get; set;}
    public string Description {get;set;}
}

我创建了一个名为ListRights我的主视图使用editortemplate。为例如：＆lt;％= Html.EditorFor（M => m.Rights）％>。

I created an editortemplate called "ListRights" that my main view uses. For example: <%=Html.EditorFor(m => m.Rights) %>.

在ListRights.ascx，我想code是这样的：

In ListRights.ascx, I want code like this:

<table>
  <% foreach(rights access in Model)
  { %>
      <tr>
        <td>
            <%=Html.CheckBoxFor( access ) %>
        </td>
        <td>
            <%=access.Description %>
        </td>
      </tr>
  <% } %>
</table>

我知道CheckBoxFor行不工作，但我想要做的事产生相同的结果，仿佛进入了模型上的属性。

I know the CheckBoxFor line does not work, but I want to do something that generates the same result, as if access was a property on the model.

在上面的例子中，我想一切autobind的帖子。

In the above example, I would like everything to autobind on post.

我试图用伪造类似这样code中的复选框，但并不autobind：

I've tried faking the CheckBox with code similar to this, but it doesn't autobind:

<table>
  <% for(int i=0; i < Model.Count(); i++)
  { %>
      <tr>
        <td>
            <%=Html.CheckBox(string.Format("[{0}].HasAccess",i), Model.ElementAt(i).HasAccess)%>
        </td>
        <td>
            <%=access.Description %>
        </td>
      </tr>
  <% } %>
</table>

有什么建议？

推荐答案

我找到了答案，通过使用由史蒂夫·桑德森博客文章在的

I found the answer by using a blog post by Steve Sanderson at http://blog.stevensanderson.com/2010/01/28/editing-a-variable-length-list-aspnet-mvc-2-style/

使用Html.BeginCollectionItem在我的处境的工作。

Using "Html.BeginCollectionItem" worked in my situation.

我创建了权利的EditorTemplate（在我的例子）。然后加入史蒂夫的BeginCollectionItem该模板。我打电话使用Html.RenderPartial模板在史蒂夫的博客建议。

I created an EditorTemplate for rights (in my example). Then added Steve's BeginCollectionItem to that template. I called the template using Html.RenderPartial as suggested in Steve's blog.

我想用Html.EditorFor（M => m.item），但是，这并不工作，因为产品在foreach，而不是在模型中。可以在这种情况下使用EditorFor

I wanted to use Html.EditorFor(m => m.item), but that doesn't work because item is in the ForEach and not in the model. Could EditorFor be used in this case?
