介绍
重新想象 Windows 8.1 Store Apps 之新增控件

• DatePicker - 日期选择控件
• TimePicker - 时间选择控件

示例
1、演示 DatePicker 的应用
DatePickerDemo.xaml

<Page
    x:Class="Windows81.Controls.DatePickerDemo"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Windows81.Controls"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="Transparent">
        <StackPanel Margin="120 0 0 0">

            <TextBlock Name="lblMsg" FontSize="14.667" />

            <!--
                DatePicker - 日期选择控件（默认横排，需要竖排的话则设置 Orientation="Vertical" 即可）
                    Header - 控件的标题
                    DateChanged - 选中的日期发生变化时所触发的事件
            -->
            <DatePicker x:Name="datePicker" Header="Date" DateChanged="datePicker_DateChanged" Margin="0 20 0 0" />

            <!--
                通过格式模板（format templates）设置 DatePicker 的显示格式
            -->
            <DatePicker DayFormat="day" MonthFormat="month.numeric" YearFormat="year.abbreviated" Margin="0 20 0 0" />

            <!--
                通过格式模式（format patterns）设置 DatePicker 的显示格式
            -->
            <DatePicker DayFormat="{}{day.integer}({dayofweek.abbreviated})" MonthFormat="{}{month.integer(2)}" YearFormat="{}{year.full}" Margin="0 20 0 0" />
            <DatePicker DayFormat="{}{day.integer}日 ({dayofweek.abbreviated})" MonthFormat="{}{month.integer(2)}月" YearFormat="{}{year.full}年" Margin="0 20 0 0" />

            <!--

            -->

        </StackPanel>
    </Grid>

DatePickerDemo.xaml.cs

/*
 * DatePicker - 日期选择控件
 */

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

namespace Windows81.Controls
{
    public sealed partial class DatePickerDemo : Page
    {
        public DatePickerDemo()
        {
            this.InitializeComponent();

            this.Loaded += DatePickerDemo_Loaded;
        }

        void DatePickerDemo_Loaded(object sender, RoutedEventArgs e)
        {
            // Date - DatePicker 控件当前显示的日期
            datePicker.Date = DateTimeOffset.Now.AddMonths(1);

            // MinYear - DatePicker 控件所允许选择的最小的年份
            datePicker.MinYear = DateTimeOffset.Now.AddYears(-20);
            // MaxYear - DatePicker 控件所允许选择的最大的年份
            datePicker.MaxYear = DateTimeOffset.Now.AddYears(20);

            // YearVisible -  是否显示 year 选择框
            datePicker.YearVisible = true;
            // MonthVisible -  是否显示 month 选择框
            datePicker.MonthVisible = true;
            // DayVisible -  是否显示 day 选择框
            datePicker.DayVisible = true;

            // CalendarIdentifier - DatePicker 控件所使用的日历系统（Gregorian, Hebrew, Hijri, Japanese, Julian, Korean, Taiwan, Thai, UmAlQura）
            datePicker.CalendarIdentifier = CalendarIdentifiers.Gregorian;
        }

        // DatePicker 控件所选择的日期发生了变化
        private void datePicker_DateChanged(object sender, DatePickerValueChangedEventArgs e)
        {
            // e.OldDate - 原日期
            // e.NewDate - 新日期
            lblMsg.Text = e.NewDate.ToString("yyyy-MM-dd hh:mm:ss");
        }
    }
}

2、演示 TimePicker 的应用
TimePickerDemo.xaml

<Page
    x:Class="Windows81.Controls.TimePickerDemo"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Windows81.Controls"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="Transparent">
        <StackPanel Margin="120 0 0 0">

            <TextBlock Name="lblMsg" FontSize="14.667" />

            <!--
                TimePicker - 时间选择控件（默认横排，需要竖排的话则设置 Orientation="Vertical" 即可）
                    Header - 控件的标题
                    TimeChanged - 选中的时间发生变化时所触发的事件
            -->
            <TimePicker Name="timePicker" Header="Time" TimeChanged="timePicker_TimeChanged" Margin="0 20 0 0" />

            <TimePicker Name="timePicker2" Header="Time" Margin="0 20 0 0" />

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

TimePickerDemo.xaml.cs

/*
 * TimePicker - 时间选择控件
 */

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

namespace Windows81.Controls
{
    public sealed partial class TimePickerDemo : Page
    {
        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
            timePicker.Time = new TimeSpan(16, 0, 0);

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

            // ClockIdentifier - 小时制式，ClockIdentifiers.TwelveHour（12HourClock），12 小时制
            timePicker.ClockIdentifier = ClockIdentifiers.TwelveHour;
            // ClockIdentifier - 小时制式，ClockIdentifiers.TwentyFourHour（24HourClock），24 小时制
            timePicker2.ClockIdentifier = ClockIdentifiers.TwentyFourHour;
        }

        // TimePicker 控件所选择的时间发生变化时所触发的事件
        private void timePicker_TimeChanged(object sender, TimePickerValueChangedEventArgs e)
        {
            // e.OldTime - 原时间
            // e.NewTime - 新时间
            lblMsg.Text = e.NewTime.ToString("c");
        }
    }
}
