Question

datetime 下面的代码在.Net 3.5中运行良好，但在.Net 4.0中，在标签显示后，日历文本框上会有一段时间。当焦点在日历文本上时盒子，时间不适合。只有在标签显示时间出现后，如附图所示。我希望时间参与其中。

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}" >

<Style x:Key="XamDateTimeEditor.SimpleStyle"

我在这台机器上没有DLL来验证我的答案，但根据Infragistics' help，您应该将Mask属性设置为{date}。如果我从here正确理解，它应该看起来像这样：

<jkdp:XamDateTimeEditor 
                    .....
                    Mask="{}{date}"
                    ..... />

如果要对使用此样式的所有控件使用相同的Mask，请将此setter添加到样式中：

<Setter Property="Mask" Value="{}{date}"/>

这将强制编辑器使用应用程序文化定义的短日期掩码。您可以根据MSDN's Custom Date and Time Format Strings

中解释的StringFormat约定来设计自己的掩码

如何在XAML中跳出后从日历文本框中删除日期时间
