Question

我正在尝试创建一个可滚动的文本块。但它似乎没有用。我应该怎么做呢？以下是我的代码：

    <Grid x:Name="ContentGrid" Grid.Row="1">
        <ScrollViewer>
        <TextBlock Height="517" HorizontalAlignment="Left" Margin="33,16,0,0" Name="textBlockRules" Text="" VerticalAlignment="Top" Width="414" FontSize="25" TextWrapping="Wrap" /></ScrollViewer>

Answer 1

即使你没有明确提到，我猜你的目的是展示一些大文字而不会被砍掉。

对于这样的要求，stackoverflow上有一些有用的线程： 1. Need to show large amount of text on windows phone 7 screen 2. Programmatically determining max fit in textbox (WP7)

另一方面，如果你想要的只是序列中的文本块，你可以使用数据绑定到列表的ListBox。

Answer 2

您必须设置ScrollViewer的最大高度，并可以将滚动条的可见性设置为自动。

以下是msdn：

中的示例

<ScrollViewer Height="200" Width="200" HorizontalScrollBarVisibility="Auto" Canvas.Top="60" Canvas.Left="340">
<TextBlock Width="300" TextWrapping="Wrap" 
    Text="I am the very model of a modern Major-General, I've information vegetable, animal, and mineral, I know the kings of England, and I quote the fights historical, From Marathon to Waterloo, in order categorical; I'm very well acquainted, too, with matters mathematical, I understand equations, both the simple and quadratical, About binomial theorem I'm teeming with a lot o' news, With many cheerful facts about the square of the hypotenuse." />
</ScrollViewer>

Answer 3

将scrollviewer Horizontal Bar设置为visibal，使文本框伸展并确保文本足够长，如下所示：

    <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" Name="Scroller">
        <TextBlock HorizontalAlignment="Stretch" VerticalAlignment="Stretch" MinWidth="100" Width="{Binding ElementName=Scroller, Path=ViewportWidth}"
        TextWrapping="Wrap" Text="Some really long text that should probably wordwrap when you resize the window." />
</ScrollViewer>
