Unfortunately the DatePicker control currently does not support free DateTime formats.

If this is something you're interested in seeing up support in future version of DatePicker, please create a codeplex feature request that suggests that.
<a href="http://silverlight.codeplex.com/WorkItem/Create.aspx" rel="noreferrer">http://silverlight.codeplex.com/WorkItem/Create.aspx</a>

Just to point out that the new Silverlight Toolkit March 2009 TimePicker &amp; TimeUpDown controls do support a full range of globalization options. One of those include free DateTime formats. So it is just a matter of public interest on whether or not we port that ability back to DatePicker. 
Have a look at the format for TimePicker @ 
<a href="http://silverlight.codeplex.com/Wiki/View.aspx?title=Silverlight%20Toolkit%20Overview%20Part%201#TimePicker" rel="noreferrer">http://silverlight.codeplex.com/Wiki/View.aspx?title=Silverlight%20Toolkit%20Overview%20Part%201#TimePicker</a>

In the meanwhile, The best workaround is to either change the local culture or the format on the local culture.

<pre><code> public App()
 {
 Thread.CurrentThread.CurrentCulture = new CultureInfo("nl-NL");
</code></pre>

or change the format on the local culture.

<pre><code> public App()
 {
 Thread.CurrentThread.CurrentCulture = (CultureInfo) Thread.CurrentThread.CurrentCulture.Clone();
 Thread.CurrentThread.CurrentCulture.DateTimeFormat.ShortDatePattern = "D/m/yyyy";
</code></pre>

blocks|key|1642263|text|您应该定义一个自定义控件模板，并编辑datepicker控件的textbox以设置文本格式。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1642264|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|$]]

You should define a custom control template and edit the textbox of the datepicker control to format the text.

blocks|key|1642330|text|您可以只隐藏控件文本框(宽度较小)，公开您自己的控件(可选地将IsEnabled设置为false)，并使用元素绑定和转换器。如果您使用的是MVVM，则将DataContext设置为您的ViewModel。我认为另一种选择是重写DataTemplate，使其不包含文本框，并执行相同的操作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1642331|<StackPanel+Orientation="Horizontal"+Height="22">
++++++<TextBox+x:Name="textBox2"+Width="106"+Text="{Binding+ElementName=datePicker2,+Path=SelectedDate,+Mode=TwoWay,+Converter={StaticResource+internationalDateTimeFormatConverter}}"+/>
++++++<controls:DatePicker+x:Name="datePicker2"+IsTabStop="False"+SelectedDate="{Binding+TargetDatePicker,+Mode=TwoWay,+NotifyOnValidationError=true,+ValidatesOnExceptions=true}"+Width="23"+HorizontalAlignment="Left"+/>
</StackPanel>|code-block|syntax|javascript|1642332|更新:从文本框到日期选择器的TwoWay绑定运行良好，但它不更新ViewModel属性。因此，我将设置IsEnabled=False并将其命名为good。|1642333|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

You could just hide the controls textbox (with a smaller width), expose you're own (optionally set the IsEnabled to false) and use an Element binding and Converter. If you're using MVVM, then set the DataContext to your ViewModel. I suppose another option would be to overwrite the DataTemplate to not include the text box and do the same idea. 

<pre><code>&lt;StackPanel Orientation="Horizontal" Height="22"&gt;
 &lt;TextBox x:Name="textBox2" Width="106" Text="{Binding ElementName=datePicker2, Path=SelectedDate, Mode=TwoWay, Converter={StaticResource internationalDateTimeFormatConverter}}" /&gt;
 &lt;controls:DatePicker x:Name="datePicker2" IsTabStop="False" SelectedDate="{Binding TargetDatePicker, Mode=TwoWay, NotifyOnValidationError=true, ValidatesOnExceptions=true}" Width="23" HorizontalAlignment="Left" /&gt;
&lt;/StackPanel&gt;
</code></pre>

UPDATE:
The TwoWay binding from the text box to the the date picker works well, but it doesn't update the ViewModel Property. So I'm going to set the IsEnabled=False and call it good.

blocks|key|1427551|text|我注意到这是一个有答案的问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1427552|但我想把this+link通知给我最近开始创建的Silverlight5控件工具包。它包含(在其他控件中)一个DateTimeBox控件，在该控件中您可以在同一个控件中同时处理日期和时间。目前，它还在开发中，但它应该可以用于大多数场景。|offset|length|1427553|entityMap|0|LINK|mutability|MUTABLE|url|http://mmtoolkitsl.codeplex.com/^0|0|4|9|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

I notice this is an answered question.

But I would like to notify about <a href="http://mmtoolkitsl.codeplex.com/" rel="nofollow">this link</a> to a Silverlight 5 control toolkit I have recently started creating. It contains (among other controls) a DateTimeBox control in which you can handle both date and time within the same control. At this point, it is still under development, but it should be usable for most scenarios.

This works great:

<pre><code>&lt;my:DatePicker IsTodayHighlighted="True" Width="200"&gt;
&lt;/my:DatePicker&gt; 
</code></pre>

But I want to format the date, something like this:

<pre><code>&lt;my:DatePicker IsTodayHighlighted="True" Width="200" Format="yyyy-mm-dd"&gt;
&lt;/my:DatePicker&gt; 
</code></pre>

Anyone know the syntax for this?
