Try tagging it with:

</code></pre>

blocks|key|280514|text|你试过这个吗？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|280515|[DataType(DataType.Date)]|code-block|syntax|javascript|280516|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|$]]

Did you try this? 

<pre><code>[DataType(DataType.Date)]
</code></pre>

blocks|key|276921|text|在MVC4中，您可以像下面这样使用TextBoxFor轻松完成此操作。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|276922|@Html.TextBoxFor(m+=>+m.StartDate,+"{0:MM/dd/yyyy}",+new+{+@class+=+"form-control+default-date-picker"+})|code-block|syntax|javascript|276923|因此，您不需要在模型或视图模型类中使用任何数据注释|276924|entityMap^0|H|A|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|R|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|S|8|@]|D|@]|E|$]]|$1|M|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|N|$]]

In mvc 4 you can easily do it like following using <code>TextBoxFor</code>..

<pre><code>@Html.TextBoxFor(m =&gt; m.StartDate, "{0:MM/dd/yyyy}", new { @class = "form-control default-date-picker" })
</code></pre>

So, you don't need to use any data annotation in model or view model class

blocks|key|3196969|text|如果您的数据字段已经是DateTime数据类型，则不需要使用[DataType(DataType.Date)]作为批注；只需使用：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3196970|[DisplayFormat(ApplyFormatInEditMode+=+true,+DataFormatString+=+"{0:MM/dd/yyyy}")]|code-block|syntax|javascript|3196971|在jQuery上，对您的日历使用日期选择器|3196972|++++$(document).ready(function+()+{

If your data field is already a DateTime datatype, you don't need to use <code>[DataType(DataType.Date)]</code> for the annotation; just use:

<pre><code>[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
</code></pre>

on the jQuery, use datepicker for you calendar

<pre><code> $(document).ready(function () {
 $('#StartDate').datepicker();
 });
</code></pre>

on your HTML, use <code>EditorFor</code> helper:

<pre><code> @Html.EditorFor(model =&gt; model.StartDate)
</code></pre>

blocks|key|3196862|text|像这样应用DataAnnotation：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3196863|[DisplayFormat(DataFormatString+=+"{0:MMM+dd,+yyyy}")]|code-block|syntax|javascript|3196864|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|$]]

Apply DataAnnotation like:

<pre><code>[DisplayFormat(DataFormatString = "{0:MMM dd, yyyy}")]
</code></pre>

blocks|key|274950|text|使用这个，但它是一个完整的解决方案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|274951|[DataType(DataType.Date)]

Use this, but it's a complete solution:

<pre><code>[DataType(DataType.Date)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
</code></pre>

blocks|key|276913|text|使用EditorFor而不是TextBoxFor|type|unstyled|depth|inlineStyleRanges|entityRanges|data|276914|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

After Commenting

<pre><code> // [DataType(DataType.DateTime)] 
</code></pre>

Use the Data Annotation Attribute:

<pre><code>[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd/MM/yyyy}")]
</code></pre>

blocks|key|276957|text|这对我很管用|type|unstyled|depth|inlineStyleRanges|entityRanges|data|276958|[DataType(DataType.DateTime)]

That works for me

<pre><code>[DataType(DataType.DateTime)]
[DisplayFormat(DataFormatString = "{0:dd-MM-yyyy}", ApplyFormatInEditMode = true)]
</code></pre>

blocks|key|2983530|text|在创建模型的时候使用下面的代码设置你的属性，我认为你的问题会是solved..and，时间不会出现在database.you中，不需要添加任何注释。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2983531|private+DateTime?+dob;
++++++++public+DateTime?+DOB
++++++++{
++++++++++++get

set your property using below code at the time of model creation i think your problem will be solved..and the time are not appear in database.you dont need to add any annotation.

<pre><code>private DateTime? dob;
 public DateTime? DOB
 {
 get
 {
 if (dob != null)
 {
 return dob.Value.Date;
 }
 else
 {
 return null;
 }

 }
 set { dob = value; }
 }
</code></pre>

blocks|key|3196983|text|这是我最喜欢的在你的模型中使用anotations的方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3196984|[DisplayFormat(DataFormatString+=+"{0:dd/MM/yyy}")]|code-block|syntax|javascript|3196985|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|$]]

This is my favourite way to do that with anotations in your model:
<pre><code>[DisplayFormat(DataFormatString = &quot;{0:dd/MM/yyy}&quot;)]
</code></pre>

I have this attribute in my view model:

<pre><code>[DataType(DataType.DateTime)]
public DateTime? StartDate { get; set; }
</code></pre>

If I want to display the date, or populate a textbox with the date, I have these:

<pre><code>&lt;%: Model.StartDate %&gt;

&lt;%: Html.TextBoxFor(m =&gt; m.StartDate) %&gt;
</code></pre>

Whenever the date is displayed, it's displayed like: 01/01/2011 12:00:00 AM

But I'd like to only display 01/01/2011

Is there a way to apply a display format with data annotations? I don't want to have to go to every instance where I display a date, and add some code to format it.

Assign format of DateTime with data annotations?

我的视图模型中有以下属性：[DataType(DataType.DateTime)]public DateTime? StartDate { get; set; }如果我想要显示日期，或者用日期填充文本框，我有以下方法：<%: Model.StartDate %><%: Html.TextBoxFor(m => m.StartDate) %>无论何时显示日期，都会显示为：01/01/2011 12
