示例
1、CalendarView 的示例
Controls/DateControl/CalendarViewDemo.xaml

<Page
x:Class="Windows10.Controls.DateControl.CalendarViewDemo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Windows10.Controls.DateControl"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"

xmlns:common="using:Windows10.Common">

<Page.Resources>
<common:NullableBooleanToBooleanConverter x:Key="NullableBooleanToBooleanConverter" />
</Page.Resources>

<Grid Background="Transparent">
<StackPanel Margin="10 0 10 10">

<CheckBox Name="chkIsOutOfScopeEnabled" Margin="5" Content="IsOutOfScopeEnabled" IsChecked="True" />
<CheckBox Name="chkIsGroupLabelVisible" Margin="5" Content="IsGroupLabelVisible" IsChecked="True" />
<CheckBox Name="chkIsTodayHighlighted" Margin="5" Content="IsTodayHighlighted" IsChecked="True" />
<ComboBox x:Name="cmbSelectionMode" Margin="5" PlaceholderText="SelectionMode" SelectionChanged="cmbSelectionMode_SelectionChanged">
<ComboBoxItem>None</ComboBoxItem>
<ComboBoxItem>Single</ComboBoxItem>
<ComboBoxItem>Multiple</ComboBoxItem>
</ComboBox>
<ComboBox x:Name="cmbDisplayMode" Margin="5" PlaceholderText="DisplayMode" SelectionChanged="cmbDisplayMode_SelectionChanged">
<ComboBoxItem>Month</ComboBoxItem>
<ComboBoxItem>Year</ComboBoxItem>
<ComboBoxItem>Decade</ComboBoxItem>
</ComboBox>
<ComboBox x:Name="cmbFirstDayOfWeek" Margin="5" PlaceholderText="FirstDayOfWeek" SelectionChanged="cmbFirstDayOfWeek_SelectionChanged">
<ComboBoxItem>Sunday</ComboBoxItem>
<ComboBoxItem>Monday</ComboBoxItem>
<ComboBoxItem>Tuesday</ComboBoxItem>
<ComboBoxItem>Wednesday</ComboBoxItem>
<ComboBoxItem>Thursday</ComboBoxItem>
<ComboBoxItem>Friday</ComboBoxItem>
<ComboBoxItem>Saturday</ComboBoxItem>
</ComboBox>

<!--
CalendarView - 日历控件
IsOutOfScopeEnabled - 是否以不同的颜色显示范围外的日历项
IsGroupLabelVisible - 是否在月的第一天或年的第一月的日历项中显示月份或年份
IsTodayHighlighted - 是否高亮显示当天日历项
FirstDayOfWeek - 指定每周的第一天是周几
SelectionMode - 日历的选择模式(None - 禁止选择, Single - 单选, Multiple - 多选)
DisplayMode - 日历的显示模式(Month - 月, Year - 年, Decade - 十年)
Language - 日历上的显示语言
CalendarIdentifier - 控件使用的日历系统,一个字符串值,在 CalendarIdentifiers 类中有封装
SelectedDatesChanged - 选中的日期发生变化时触发的事件
CalendarViewDayItemChanging - 加载日历项时触发的事件

其他大部分属性都是用于配置显示样式的了,具体说明详见文档
另外,在 CalendarView 控件中没有属性可以直接设置当天日历项的背景色(在本例的 code-behind 中给出了解决办法)
-->
<CalendarView Name="calendarView" Margin="5"
IsOutOfScopeEnabled="{x:Bind chkIsOutOfScopeEnabled.IsChecked, Mode=TwoWay, Converter={StaticResource NullableBooleanToBooleanConverter}}"
IsGroupLabelVisible="{x:Bind chkIsGroupLabelVisible.IsChecked, Mode=TwoWay, Converter={StaticResource NullableBooleanToBooleanConverter}}"
IsTodayHighlighted="{x:Bind chkIsTodayHighlighted.IsChecked, Mode=TwoWay, Converter={StaticResource NullableBooleanToBooleanConverter}}"
FirstDayOfWeek="Sunday"
SelectionMode="Single"
DisplayMode="Month"
Language="zh-cn"
CalendarIdentifier="GregorianCalendar"
SelectedDatesChanged="calendarView_SelectedDatesChanged"
CalendarViewDayItemChanging="calendarView_CalendarViewDayItemChanging" />

</StackPanel>
</Grid>
</Page>


Controls/DateControl/CalendarViewDemo.xaml.cs

/*
* CalendarView - 日历控件(继承自 Control, 请参见 /Controls/BaseControl/ControlDemo/)
*
* CalendarViewDayItem - 日历项控件(继承自 Control, 请参见 /Controls/BaseControl/ControlDemo/)
*     Date - 获取此日历项的日期(只读)
*     IsBlackout - 此日历项是否不可用(通过 CalendarView 的 BlackoutForeground 属性可配置不可用日历项的前景色)
*/

using System;
using Windows.UI;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Media;

namespace Windows10.Controls.DateControl
{
public sealed partial class CalendarViewDemo : Page
{
public CalendarViewDemo()
{
this.InitializeComponent();
}

private void cmbSelectionMode_SelectionChanged(object sender, SelectionChangedEventArgs e)

{
calendarView.DisplayMode = (CalendarViewDisplayMode)Enum.Parse(typeof(CalendarViewDisplayMode), (e.AddedItems[0] as ComboBoxItem).Content.ToString());
}

private void cmbFirstDayOfWeek_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
calendarView.FirstDayOfWeek = (Windows.Globalization.DayOfWeek)Enum.Parse(typeof(Windows.Globalization.DayOfWeek), (e.AddedItems[0] as ComboBoxItem).Content.ToString());
}

// 加载日历项时触发的事件
private void calendarView_CalendarViewDayItemChanging(CalendarView sender, CalendarViewDayItemChangingEventArgs args)
{
// 如果当前加载的日历项时当天的话
if (args.Item.Date.Date.Equals(DateTime.Now.Date))
{
// 修改日历项的背景色(在 CalendarView 控件中没有属性可以直接设置当天日历项的背景色)
// 另外,还有一些日历项的样式无法通过 CalendarView 直接设置,那么都可以考虑像这样做
args.Item.Background = new SolidColorBrush(Colors.Orange);
}
}

// 选中的日期发生变化时触发的事件
private void calendarView_SelectedDatesChanged(CalendarView sender, CalendarViewSelectedDatesChangedEventArgs args)

// calendarView.SelectedDates - 当前被选中的日期集合
}
}
}


2、DatePicker 的示例

<TextBlock Name="lblMsg" />

<!--
DatePicker - 日期选择控件
Header - 可以设置一个纯文本,不能命中测试,空 Header 的话不会占用任何空间
HeaderTemplate - 可以将 Header 设置为任何 xaml,且支持命中测试

lblMsg.Text = $"OldDate - {e.OldDate.ToString("yyyy-MM-dd hh:mm:ss")}, NewDate - {e.NewDate.ToString("yyyy-MM-dd hh:mm:ss")}";
}
}
}


3、TimePicker 的示例

using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;

namespace Windows10.Controls.DateControl
{

{
public TimePickerDemo()
{
this.InitializeComponent();

this.Loaded += TimePickerDemo_Loaded;
}

void TimePickerDemo_Loaded(object sender, RoutedEventArgs e)
{
// Time - TimePicker 控件当前显示的时间
timePicker1.Time = new TimeSpan(16, 0, 0);

// MinuteIncrement - 分钟选择框的分钟增量(0, 15, 30, 45)
timePicker1.MinuteIncrement = 15;

// ClockIdentifier - 小时制式,ClockIdentifiers.TwelveHour(12HourClock),12 小时制
timePicker1.ClockIdentifier = ClockIdentifiers.TwelveHour;

// ClockIdentifier - 小时制式,ClockIdentifiers.TwentyFourHour(24HourClock),24 小时制
timePicker2.ClockIdentifier = ClockIdentifiers.TwentyFourHour;
}

// TimePicker 控件选中的时间发生变化时触发的事件
