Windows runtime 如何在垂直线Windows Phone 8.1中使用ScrollView控件

我希望我的滚动视图不向下滚动，是的，从左右两侧滚动，就像一个轴一样

<ScrollViewer Height="100" VerticalAlignment="Top" 
    VerticalScrollBarVisibility="Visible" VerticalScrollMode="Enabled" 
    AllowDrop="False" BringIntoViewOnFocusChange="True"
    HorizontalScrollMode="Disabled" IsHoldingEnabled="True" >
        <Grid Grid.Row="1" x:Name="ContentRoot" Height="90" Width="386" />
</ScrollViewer>

<ScrollViewer Height="100" VerticalAlignment="Top" VerticalScrollMode="Disabled" HorizontalScrollBarVisibility="Auto" 
              HorizontalScrollMode="Enabled" Background="Blue">
    <TextBlock FontSize="50" Text="Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor" />
</ScrollViewer>
