Question

我有一个有两个约会的模特，我按照建议＆＃34; 08/07/2013 08：00：00＆＃34;和CurrentFocusDate＆＃34; 08/07/2013 00：00：00＆＃34;然而某些地方出现了问题，因为在页面中它们呈现的方式不同（请参阅下面的输出）任何人都知道为什么两个alsmot相同的属性会以不同的方式呈现？

模型

public AdminNoteViewModel
{
    [HiddenInput(DisplayValue = false)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}")]
    public DateTime ProposedDateTime { get; set; }

    [HiddenInput(DisplayValue = true)]
    [DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}")]
    public DateTime CurrentFocusDate { get; set; }

    [HiddenInput(DisplayValue = true)]
    public string NavigationLink { get; set; }
}

查看

@Html.EditorFor(model => model.ProposedDateTime)
@Html.ValidationMessageFor(model => model.ProposedDateTime)

@Html.EditorFor(model => model.CurrentFocusDate)

@Html.HiddenFor(model => model.NavigationLink)

控制器

 public ActionResult AddNote(DateTime proposedEventDateTime, long productId, DateTime currentFocusDate, string navigationLink)
 { 
     var model = new AdminNoteViewModel
     {
         ProductId = productId,
         ProposedDateTime = proposedEventDateTime,
         CurrentFocusDate = currentFocusDate,
         NavigationLink = navigationLink
     };

     return View(model);
 }

这是呈现的源

<input data-val="true" data-val-date="The field ProposedDateTime must be a date." data-val-required="The ProposedDateTime field is required." id="ProposedDateTime" name="ProposedDateTime" type="hidden" value="07/08/2013 08:00:00" />
<span class="field-validation-valid" data-valmsg-for="ProposedDateTime" data-valmsg-replace="true"></span>

<input data-val="true" data-val-date="The field CurrentFocusDate must be a date." data-val-required="The CurrentFocusDate field is required." id="CurrentFocusDate" name="CurrentFocusDate" type="hidden" value="08/07/2013 00:00:00" />

<input id="NavigationLink" name="NavigationLink" type="hidden" value="Civica.DrugAdmin.UI.Models.AdminNoteViewModel" />

当我调试时，浏览到视图的模型已经正确格式化了两个日期，但是当它们在页面上呈现时，其中一个（currentFocusDate）被切换。

按照设计，HiddenFor助手（最终由EditorFor使用）在呈现其值时始终使用当前的区域性格式。如果要覆盖此行为，可以编写自定义编辑器模板（~/Views/Shared/EditorTemplates/HiddenInput.cshtml）：

@if (!ViewData.ModelMetadata.HideSurroundingHtml) 
{
    @ViewData.TemplateInfo.FormattedModelValue
}
@Html.Hidden("", ViewData.TemplateInfo.FormattedModelValue)

然后您就可以使用DisplayFormat属性指定格式并覆盖当前文化的格式：

[HiddenInput(DisplayValue = false)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
public DateTime ProposedDateTime { get; set; }

奇怪的MVC日期问题
