在XAML中跳出后，如何从日历文本框中删除datetime中的时间

问题描述

|| 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}\"

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}\"
                    ..... />

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}\"/>

这将迫使编辑者使用应用程序区域性所定义的短日期掩码。您可以根据MSDN的“自定义日期和时间格式字符串”中说明的StringFormat约定设计自己的掩码。
