Question

我有一个基于被提名者的Viewmodel。我可以为视图模型提供多个提名。

我想从视图中填充Ilist。这是我的viewmodels

public class DebitViewModel:IValidatableObject
{
    public string AgentName { get; set; }
    public Debit Debit { get; set; }

    public Policy Policy { get; set; }
    public PolicyType PolicyType { get; set; }
    public Customer Customer { get; set; }     

    public IList<PolicyType> PolicyTypes { get; set; }
    public List<Nominee> Nominees { get; set; }
    public Dictionary<int,string> OccupationTypes { get; set; }        
}

我想在按提交时自动填充所有Nominess。那么我应该如何通过视图创建并使其自动填充List？而不是serparate对象？

Answer 1

您可以使用编辑器模板：

@model DebitViewModel
@using (Html.BeginForm())
{
    ... some input fields for the other properties that we are not interested in

    @Html.EditorFor(x => x.Nominees)

    <button type="submit">OK</button>
}

然后为Nominee模型（~/Views/Shared/EditorTemplates/Nominee.cshtml）定义自定义编辑器模板，该模板将自动为Nominees集合的每个元素呈现：

@model Nominee

<div>
    @Html.EditorFor(x => x.FirstName)
    @Html.EditorFor(x => x.LastName)
    ...
</div>

Answer 2

例如，Nominee看起来像

public class Nominee{
 public int Id{get;set;}
 public string Name{get;set;}
 public int Age {get;set;}
}

视图看起来像

@for (int i = 0; i < Model.Nominees.Count(); i++)
{ 
<tr>                                                           
  <td>@Html.TextBoxFor(m => m.Nominees[i].Name)</td>
  <td>@Html.TextBoxFor(m => m.Nominees[i].Age)</td>
</tr>
}
