背水一战 Windows 10 (44) - 控件(日期类): CalendarView, DatePicker, TimePicker



作者:webabcd


介绍
背水一战 Windows 10 之 控件(日期类)

  • CalendarView
  • DatePicker
  • TimePicker



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:common="using:Windows10.Common">

    <Page.Resources>

    </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)

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