C# DisplayTemplate不适用于可为空的日期时间

下面是我为可为空的

DateTime

属性创建的显示模板。我将其存储在

Views\Shared\EditorTemplates

文件夹中。此模板的名称为

DisplayNullableDate.cshtml

@model DateTime?

@Html.Label("", (Model.HasValue ? Model.Value.ToString("MM/dd/yyyy") : string.Empty), new { @class = "form-control" })

我在我的

详细信息

页面上这样调用此模板，但它不起作用。我仍然能得到它在网页上显示的时间

<tr>
    <td>@Html.DisplayFor(model => model.RelationshipCode1.EffectiveDate, "DisplayNullableDate", new { @class = "relCodeDate1" })</td>
    <td>@Html.DisplayFor(model => model.RelationshipCode1.RelationshipId, new { @class = "relDistCode1", maxlength = 3 })</td>
</tr>
<tr>
    <td>@Html.DisplayFor(model => model.RelationshipCode2.EffectiveDate, "DisplayNullableDate", new { @class = "relCodeDate2" })</td>
    <td>@Html.DisplayFor(model => model.RelationshipCode2.RelationshipId, new { @class = "relDistCode2", maxlength = 3 })</td>
</tr>
<tr>
    <td>@Html.DisplayFor(model => model.RelationshipCode3.EffectiveDate, "DisplayNullableDate", new { @class = "relCodeDate3" })</td>
    <td>@Html.DisplayFor(model => model.RelationshipCode3.RelationshipId, new { @class = "relDistCode3", maxlength = 3 })</td>
</tr>
<tr>
    <td>@Html.DisplayFor(model => model.RelationshipCode4.EffectiveDate, "DisplayNullableDate", new { @class = "relCodeDate4" })</td>
    <td>@Html.DisplayFor(model => model.RelationshipCode4.RelationshipId, new { @class = "relDistCode4", maxlength = 3 })</td>
</tr>
<tr>
    <td>@Html.DisplayFor(model => model.RelationshipCode5.EffectiveDate, "DisplayNullableDate", new { @class = "relCodeDate5" })</td>
    <td>@Html.DisplayFor(model => model.RelationshipCode5.RelationshipId, new { @class = "relDistCode5", maxlength = 3 })</td>
</tr>

编辑

为了更好地衡量，这里是当前的模型属性。不幸的是，我也不能让这个显示格式装饰工作

    [DisplayName("Effective Date")]
    [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
    public Nullable<System.DateTime> EffectiveDate { get; set; }

[DisplayName（“生效日期”）]
[DisplayFormat（ApplyFormatInEditMode=true，DataFormatString=“{0:MM/dd/yyyy}”）]
公共可空的EffectiveDate{get；set；}

我认为您需要使用

[UIHint（“NullableDate”）]

属性来装饰模型的属性。

当我在DateTime字段中有空值时，这个显示模板就为我工作了：

@model DateTime?

@((@Model != null) ?  Model.Value.ToString("MM/dd/yyyy") : "{n/a}" )

---

当值为null时，它将替换为字符串：{n/a}

Hm。。。目前没有，但是

NullableDate

模板可以正常工作。刚刚发布了模型属性。

@model DateTime?

@((@Model != null) ?  Model.Value.ToString("MM/dd/yyyy") : "{n/a}" )
