            <CheckBox Name="chkIsSticky" Margin="5" Content="IsSticky" IsChecked="False" Checked="chkIsSticky_Checked" Unchecked="chkIsSticky_Unchecked" />
            <StackPanel Margin="5" Orientation="Horizontal">
                <RadioButton Name="radioButtonMinimal" GroupName="myGroup" Content="AppBarClosedDisplayMode.Minimal" Checked="radioButtonMinimal_Checked" />
                <RadioButton Name="radioButtonHidden" GroupName="myGroup" Margin="10 0 0 0" Content="AppBarClosedDisplayMode.Hidden" Checked="radioButtonHidden_Checked" />

            <Button Name="btnClose" Margin="5" Content="关闭 CommandBar" Click="btnClose_Click" />

        </StackPanel>
    </Grid>

    <!--
        Page.BottomAppBar - 下方应用程序栏控件
        Page.TopAppBar - 上方应用程序栏控件
    
        CommandBar - 应用程序栏控件。相对于 AppBar 来说, CommandBar 易用性强,扩展性弱(在 CommandBar 内只能包含 AppBarButton, AppBarToggleButton, AppBarSeparator)。CommandBar 继承自 AppBar
            IsOpen - 是否打开 CommandBar
            IsSticky - 是否是粘性的 CommandBar(即在点击非 CommandBar 区域时,是否不会关闭 CommandBar),默认值 false
            ClosedDisplayMode - 应用程序栏关闭状态下的显示模式
                Minimal - 最小化模式,只显示省略号
                Hidden - 隐藏
                Compact - 显示 PrimaryCommands 中的按钮的 icon,但不显示其 label,且 SecondaryCommands 中的按钮不会显示,此值为默认值(AppBar 的 ClosedDisplayMode 的默认值为 Minimal)
            Opening, Opened, Closing, Closed - 几个事件,不解释
    
        注:无法手动设置 CommandBar 中的 AppBarButton, AppBarToggleButton, AppBarSeparator 的 IsCompact 属性,其如何设置由系统自己决定(比如 Compact 模式的关闭状态的 CommandBar 会隐藏 label,打开状态的 CommandBar 会显示 label)
