问题描述
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.该模板的名称为DisplayNullableDate.cshtml
.
Below is the the display template I created for a nullable DateTime
property. I have this stored in the Views\Shared\EditorTemplates
folder. The name of this template is DisplayNullableDate.cshtml
.
@model DateTime?
@Html.Label("", (Model.HasValue ? Model.Value.ToString("MM/dd/yyyy") : string.Empty), new { @class = "form-control" })
我在Details
页面上像这样称呼此模板,但是它不起作用.我仍然有时间在网页上显示它.
I am calling this template like so on my Details
page, however it's not working. I'm still getting the time when it's displayed on the web page.
<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>
在相同的Shared\EditorTemplates
文件夹中,我确实有另一个模板,其名称为NullableDate.cshtml
,用于同一可为空的属性.我认为这不会造成干扰,但是无论如何我都会将其发布,以防万一.
I do have another template for the same nullable property in the same Shared\EditorTemplates
folder by the name of NullableDate.cshtml
. I don't think this would interfere, however I'll post it anyway just in case.
@model DateTime?
@Html.TextBox("", (Model.HasValue ? Model.Value.ToString("MM/dd/yyyy") : string.Empty), new { @class = "form-control" })
编辑
为了很好地衡量,这里是当前状态的模型属性.不幸的是,我也无法使这种显示格式的装饰正常工作.
For good measure, here is the model property as it stands right now. Unfortunately I can't get this display format decoration to work either.
[DisplayName("Effective Date")]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
public Nullable<System.DateTime> EffectiveDate { get; set; }
推荐答案
当我在DateTime字段中具有空值时,此DisplayTemplate最终为我工作:
This DisplayTemplate ended up working for me, when I had null values in the DateTime field:
@model DateTime?
@((@Model != null) ? Model.Value.ToString("MM/dd/yyyy") : "{n/a}" )
当该值为null时,将其替换为字符串:{n/a}
When the value is null, it is replaced with the string: {n/a}
