WindowsRT DatePicker（8.1）中的可为空的值

[英]Nullable value in a WindowsRT DatePicker (8.1)

原文 2016-03-09 14:02:14 3 1 c#/ windows-runtime/ windows-store-apps/ microsoft-metro/ winrt-xaml

I can't seem to get anything working with a simple XAML project that has the DatePicker accepting a nullable value and therefore the Date/Month/Year boxes are showing this text as placeholder. 我似乎无法在具有DatePicker接受可为空值的简单XAML项目中使用任何东西，因此Date / Month / Year框将此文本显示为占位符。

Can anyone help? 有人可以帮忙吗？ I've found very little from other people on the web about this! 我从网上其他人那里发现的东西很少！

thank you 谢谢

The datepicker does not accepts null values. 日期选择器不接受空值。 Have a converter to check if the date passed is null,if yes hide the content. 让转换器检查传递的日期是否为空，如果是，则隐藏内容。
