Controls/DateControl/DatePickerDemo.xaml.cs
/* * DatePicker - 日期选择控件(继承自 Control, 请参见 /Controls/BaseControl/ControlDemo/) * YearVisible, MonthVisible, DayVisible, MinYear, MaxYear, Date, CalendarIdentifier - 详见下面示例代码中的注释 */ using System; using Windows.Globalization; using Windows.UI.Xaml; using Windows.UI.Xaml.Controls; namespace Windows10.Controls.DateControl { 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 控件使用的日历系统,一个字符串值,在 CalendarIdentifiers 类中有封装 datePicker.CalendarIdentifier = CalendarIdentifiers.Gregorian; } // DatePicker 控件选中的日期发生变化时触发的事件 private void datePicker_DateChanged(object sender, DatePickerValueChangedEventArgs e) { // e.OldDate - 原日期 // e.NewDate - 新日期 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
Controls/DateControl/TimePickerDemo.xaml
<Page x:Class="Windows10.Controls.DateControl.TimePickerDemo" 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"> <Grid Background="Transparent"> <StackPanel Margin="10 0 10 10"> <TextBlock Name="lblMsg" Margin="5" /> <!-- TimePicker - 时间选择控件 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 TimeChanged - 选中的时间发生变化时触发的事件 --> <TimePicker Name="timePicker1" Header="Time" TimeChanged="timePicker1_TimeChanged" Margin="5" /> <TimePicker Name="timePicker2" Header="Time" Margin="5" /> </StackPanel> </Grid> </Page>
Controls/DateControl/TimePickerDemo.xaml.cs
/* * TimePicker - 时间选择控件(继承自 Control, 请参见 /Controls/BaseControl/ControlDemo/) * Time, MinuteIncrement, ClockIdentifier - 详见下面示例代码中的注释 */ using System; using Windows.Globalization; using Windows.UI.Xaml; using Windows.UI.Xaml.Controls; namespace Windows10.Controls.DateControl { 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 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 private void timePicker1_TimeChanged(object sender, TimePickerValueChangedEventArgs e) { // e.OldTime - 原时间 // e.NewTime - 新时间 lblMsg.Text = $"OldTime - {e.OldTime.ToString("c")}, NewTime - {e.NewTime.ToString("c")}"; } } }
