如何解决在XAML中跳出后，如何从日历文本框中删除datetime中的时间
|| 下面的代码在.Net 3.5中工作正常，但在.Net 4.0中，分页后在日历文本框上出现了一段时间。当焦点位于日历文本框上时，时间将不显示。仅在跳出时间后才出现，如下图所示。我不希望时间参与其中。 使用的代码如下：<jkdp:XamDateTimeEditor Grid.Row=\"1\"
Grid.Column=\"1\"
KeyboardNavigation.TabIndex=\"1\"
InvalidValueBehavior=\"RetainValue\"
gcb:CommandBehavior.Event=\"LostFocus\"
gcb:CommandBehavior.Command=\"{Binding EndDateChangedCommand}\"
Style=\"{DynamicResource XamDateTimeEditor.SimpleStyle}\"
Text=\"{Binding EndDate,Mode=TwoWay,NotifyOnSourceUpdated=true}\" >

解决方法
我在这台机器上没有DLL可以验证我的答案，但是根据Infragistics的帮助，您应该将Mask属性设置为{date}。如果我从这里正确理解，它应该看起来像这样：
<jkdp:XamDateTimeEditor
.....
Mask=\"{}{date}\"
..... />
<Setter Property=\"Mask\" Value=\"{}{date}\"/>
