Why are you using <code>ApplyFormatInEditMode</code> if you have set <code>[Editable(false)]</code>? All <code>ApplyFormatInEditMode</code> does is format the date if you have it in a text box or something for editing, which you probably won't because of the aforementioned.

I was able to get the date to display correctly using the following:

<pre><code>[DisplayFormat(DataFormatString = "{0:yyyy/MM/dd}")]
public DateTime Date 
{
 get
 {
 return DateTime.Now;
 }
 set
 {
 Date = DateTime.Now;
 }
}
</code></pre>

and in the view (with resulting output):

<pre><code>@Html.DisplayFor(x =&gt; x.Date) // 2013/05/23
&lt;br /&gt;
@Model.Date // 23/05/2013 09:57:56
&lt;br /&gt;
@Html.DisplayFor(x =&gt; Model.Date) // 2013/05/23
</code></pre>

Hope this helps.

If you can't get it working on the model, you could try it on the view.
<pre><code>@Html.TextBoxFor(m =&gt; m.ValidFrom, &quot;{0:dd/MM/yyyy}&quot;, new {maxlength = 10})

blocks|key|312404|text|这对我来说很有效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|312405|在模型中：|312406|using+System.ComponentModel.DataAnnotations;

This work for me:

In the model:

<pre><code>using System.ComponentModel.DataAnnotations;

namespace Athlete.Models
{
 public class Foo
 {

 [DisplayFormat(DataFormatString = "{0:MM/dd/yyyy}")]
 public DateTime SignDate
 {
 get;
 set;
 }
 }
}
</code></pre>

And in the view:

<pre><code>&lt;td style="text-align:left;"&gt;@Html.DisplayFor(modelItem =&gt; item.SignDate)&lt;/td&gt;
</code></pre>

blocks|key|95538|text|在我的例子中，一个队友定义了一个全局显示模板(也就是~\Views\Shared\DisplayTemplates\DateTime.cshtml)，我没有意识到它在我的模型属性上优先于我的[DisplayFormat(DataFormatString+=+"{0:yyyy-MM-dd}")]。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|95539|解决方案是将我的格式字符串移动到新的共享模板中，因此属性更改为：|95540|//+see+~\Views\Shared\DisplayTemplates\DateMyFormat.cshtml+for+formatting

In my case a teammate had defined a global display template (aka <code>~\Views\Shared\DisplayTemplates\DateTime.cshtml</code>) that I didn't realize took precedence over my <code>[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}")]</code> on my model property.

The solution was to move my format string to new shared template, so the attribute changes to:

<pre><code>// see ~\Views\Shared\DisplayTemplates\DateMyFormat.cshtml for formatting
[UIHint("DateMyFormat")]
public DateTime MovementDate { get; set; }
</code></pre>

blocks|key|95552|text|您必须将该类型注释为Date|type|unstyled|depth|inlineStyleRanges|entityRanges|data|95553|[DataType(DataType.Date)]|code-block|syntax|javascript|95554|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

I had a similar issue with a datepicker which was showing the date in the wrong order. Fixed it by using the HTML 5 value field. 
<a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/date" rel="nofollow noreferrer">https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/date</a>

<pre><code>&lt;input asp-for="From" type="text" class="pickadate picker__input" value="@Model?.From.ToString("MM/dd/yyyy")"&gt;
</code></pre>

I have a property in my view model as follows:

<pre><code>[Editable(false)]
[Display(Name = "Date")]
[DisplayFormat(DataFormatString = "{0:yyyy/MM/dd}", ApplyFormatInEditMode = true)]
public DateTime MovementDate { get; set; }
</code></pre>

Yet the markup

<pre><code>&lt;td&gt;
 @Html.DisplayFor(modelItem =&gt; item.MovementDate)
&lt;/td&gt;
</code></pre>

renders the date value as <code>2013/05/15 12:00:00 AM</code>.

What am I doing wrong? My model:

<pre><code>public class WithDateModel
{
 [DisplayFormat(DataFormatString = "{0:yyyy/MM/dd}")]
 public DateTime TheDate { get; set; }
 public WithDateModel()
 {
 TheDate = DateTime.Now;
 }
}
</code></pre>

My view:

<pre><code>@model ParkPay.WebTests.Models.WithDateModel
@Html.DisplayFor(m =&gt; m.TheDate)
@section Scripts {
 @Scripts.Render("~/bundles/jqueryval")
}
</code></pre>

What gets rendered:

<pre><code>2013/05/25 02:23:37 AM
</code></pre>

Why is DisplayFormat DataFormatString not working?

我的视图模型有一个属性，如下所示：[Editable(false)][Display(Name = "Date")][DisplayFormat(DataFormatString = "{0:yyyy/MM/dd}", ApplyFormatInEditMode = true)]public DateTime Move...
