Werid MVC日期問題

Question

我有一個有兩個日期的模型，我同時通過建議的「08/07/2013 08:00:00」和CurrentFocusDate「08/07/2013 00:00:00」，但是某處會出現錯誤，因爲它們在頁面中呈現的方式不同（請參閱下面的輸出）任何人都有一個想法，爲什麼兩個alsmot相同的屬性會呈現不同的渲染？

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); 
} 

這是呈現的源

<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" /> 

當我調試時，模型的視圖兩個日期都格式正確，但是當它們在頁面上呈現時，它們中的一個（currentFocusDate）會被切換。

通過設計HiddenFor幫助器（最終被EditorFor使用）在呈現其值時始終使用當前的文化格式。如果要覆蓋此行爲，你可以寫一個自定義編輯器模板（~/Views/Shared/EditorTemplates/HiddenInput.cshtml）：

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

，然後你就可以使用DisplayFormat屬性指定的格式和替代當前區域性的格式：

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