Question

我正在编写Windows Phone 8.1应用程序（WINRT）。

我在页面中实现了 scrollviewer 。它包含 stackpanel ，其带有长文本的richtextblock 和按钮。

但问题是这个滚动查看器根本不滚动。如果我手动为此滚动查看器设置高度，则会滚动但在较高分辨率下看起来很难看。如何在没有手动高度的情况下使这个滚动查看器工作。

<ScrollViewer Name="WhyJoin_User_Content_Scroll"
                              Margin="0,10,0,10" 
                              VerticalScrollBarVisibility="Auto"
                              >
<StackPanel Orientation="Vertical">
    <RichTextBlock Name="WhyJoin_User_Content_RichTextBlock"
                    FontWeight="Light"
                    Margin="20,10,20,0" 
                    Foreground="{StaticResource DefaultTheme_DarkBlueColor}"
                    FontSize="19"
                    TextWrapping="Wrap"
                     TextAlignment="Justify">
        <RichTextBlock.Blocks>
            <Paragraph>
                <Paragraph.Inlines>
                    <Run Text=" Text Text Text Text Text Text Text Text ">
                    </Paragraph.Inlines>
                </Paragraph>
                <Paragraph>

                    <Paragraph>
                        <Paragraph.Inlines>
                            <Run Text=" Text Text Text Text Text Text Text Text "></Run>
                        </Paragraph.Inlines>

解决问题的最简单方法是将滚动查看器的高度和/或宽度绑定到ContentRoot。这在Blend中最容易完成，无论屏幕分辨率如何，您都可以自动达到所需的高度。

这就是XAML的样子

<ScrollViewer HorizontalAlignment="Left" Margin="0" VerticalAlignment="Top" Width="175" Height="{Binding ActualHeight, ElementName=ContentRoot}"/>

Scrollviewer没有高度滚动
