CheckBox的使用：

<UserControl x:Class="CheckBoxDemo.MainPage"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    d:DesignHeight="300" d:DesignWidth="400">

    <Grid x:Name="LayoutRoot" Background="White">

        <StackPanel Orientation="Vertical" x:Name="SPanel">
            <TextBlock HorizontalAlignment="Left" Text="请选择你的爱好" FontSize="14"></TextBlock>
            <TextBlock  HorizontalAlignment="Left" x:Name="txtResult"></TextBlock>
            <CheckBox  HorizontalAlignment="Left" ToolTipService.ToolTip="民以食为天" IsChecked="True" Content="做饭"/>
            <CheckBox  HorizontalAlignment="Left" ToolTipService.ToolTip="为了家人，还是干吧"  Content="拖地"/>
