How to use EditorFor inside a foreach

问题

I have a model:

public class MyListModel
{
    public int ID {get;set;}
    public List<User> Users{get;set;}
}

How do I use the Html.EditorFor method inside a foreach?

@model MyListModel
<table>
  <tr>
    <th></th>
  </tr>
  @foreach (var item in Model.Users) {
     <tr>
       <td>
          @Html.EditorFor(item.Enabled)
       </td>
     </tr>
  }
</table>

回答1:

@Html.EditorFor(x=> item.Enabled)

It's been pointed out many times that posting such a model back to server will not work in mvc by default. For properly editing with EditorFor in a loop - for should be used as in:

 @for(var i = 0; i< Model.Users.Count;i++){
      Html.EditorFor(i=>Model.Users[i])
 }

回答2:

@for (var i = 0; i < Model.Users.Count; i++)
{
<tr>
    <td>@Html.EditorFor(model => model.Users[i].Enabled)</td>
    <td>@Html.EditorFor(model => model.Users[i].FirstName)</td>
    <td>@Html.EditorFor(model => model.Users[i].LastName)</td>
</tr>
}

Plus some hidden variables for at least one property of the User are required:

@for (var i = 0; i < Model.Users.Count; i++)
{
    @Html.HiddenFor(model => model.Users[i].FirstName)
}

Not what you would call elegant but it works with respect to binding in your post action.

回答3:

Is there any other reason (example apart) for explicitly using the foreach yourself? You could make a Custom Editor (or Display) helper for User class and make @Html.EditorFor(model=>model.Users). Razor will use the foreach internally for processing each element with your Custom Helper.

Just an idea for those visiting the question with really no clue how manage this cases.
