title: Format list elements in viewmodel
body: <p>In my viewmodel I have <code>SubscriptionExpires</code> formatted as below</p>
  
  <pre><code>    public class IndexViewModel
  {
      [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dddd d MMMM yyyy}")]
      public DateTime? SubscriptionExpires { get; set; }
  
      public IEnumerable&lt;Device&gt; Devices { get; set; }
  }
  </code></pre>
  
  <p><code>Device</code> also includes a date property</p>
  
  <pre><code>    public partial class Device
  {
      [Key]
      public int DeviceId { get; set; }
      public string UserId { get; set; }
      public virtual ApplicationUser User { get; set; }
      public string DeviceName { get; set; }
      public DateTime UnlockedTo { get; set; }
  }
  </code></pre>
  
  <p>Is there any way of setting the date format for <code>UnlockedTo</code> in <code>IndexViewModel</code> or must formatting for this property be done in the view?</p>
