示例
1、ListBox 的示例
Controls/SelectionControl/ListBoxDemo.xaml

<Page
    x:Class="Windows10.Controls.SelectionControl.ListBoxDemo"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:Windows10.Controls.SelectionControl"
    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">

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

            <!--
                ListBox - 列表框控件
            -->

            <!--
                通过 xaml 方式为 ListBox 添加数据

                注：如果需要 ListBox 的 item 横向排列的话，可以参考 /Controls/CollectionControl/FlipViewDemo.xaml 中用于显示小点点的 ListBox 的实现
            -->
            <ListBox x:Name="listBox1" Margin="5" Width="200" Height="300" HorizontalAlignment="Left" VerticalAlignment="Top">
                <ListBox.Items>
                    <ListBoxItem Content="ListBoxItem1" />
                    <ListBoxItem Content="ListBoxItem2" />

                </ListBox.Items>
            </ListBox>

            <ListBox x:Name="listBox2" Margin="5" ItemsSource="{x:Bind Employees}" Width="200" Height="300" HorizontalAlignment="Left" VerticalAlignment="Top">
                <ListBox.ItemTemplate>
                    <DataTemplate x:DataType="common:Employee">
                        <StackPanel Orientation="Horizontal">
                            <TextBlock Text="{x:Bind Name}" />
                            <TextBlock Text="{x:Bind Age}" Margin="5 0 0 0" />
                        </StackPanel>
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>
            <TextBlock Name="lblMsg2" Margin="5" Width="300" TextWrapping="Wrap" />

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

Controls/SelectionControl/ListBoxDemo.xaml.cs

/*
 * ListBox - 列表框控件（继承自 Selector, 请参见 /Controls/SelectionControl/SelectorDemo.xaml）
 *     SelectionMode - 选择的模式
 *         Single - 单选（默认）
 *         Multiple - 仅通过鼠标多选
 *         Extended - 通过鼠标和辅助键（ctrl, shift）多选
 *     ScrollIntoView(object item) - 滚动到指定数据对象
 *     SelectAll() - 选中所有项
 *     SelectedItems - 获取当前选中的数据对象集合
 *
 *
 * ListBoxItem - 列表框控件的 item（继承自 SelectorItem, 请参见 /Controls/SelectionControl/SelectorDemo.xaml）

namespace Windows10.Controls.SelectionControl
{
    public sealed partial class ListBoxDemo : Page
    {
        public ObservableCollection<Employee> Employees { get; set; } = TestData.GetEmployees();

        public ListBoxDemo()
        {
            this.InitializeComponent();

            // 通过鼠标结合 ctrl键 shift键 多选
            listBox1.SelectionMode = SelectionMode.Extended;

            // 仅通过鼠标多选
            listBox2.SelectionMode = SelectionMode.Multiple;
            listBox2.Loaded += ListBox2_Loaded;
        }

        private void ListBox2_Loaded(object sender, Windows.UI.Xaml.RoutedEventArgs e)
        {
            listBox2.SelectAll();

    mc:Ignorable="d">

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

            <!--
                RadioButton - 单选框控件
                    GroupName - 单选框的组名，同一组单选框只能有一个为选中状态

                注：RadioButton 继承自 ToggleButton，关于 ToggleButton 的知识点请参见“/Controls/ButtonControl/ToggleButtonDemo.xaml”
            -->

            <RadioButton Name="rad1" GroupName="groupName1" Margin="5" IsChecked="True" Content="groupName1 - RadioButton1" />

            <!--
                CheckBox - 复选框控件

            <!--
                ToggleSwitch - 状态切换控件
                    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

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

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

        private void toggleSwitch1_Toggled(object sender, RoutedEventArgs e)
