XAML中ScrollViewer的奇怪问题

我试图在XAML中的TextBlock周围放置一个ScrollViewer（这里，TextBlock称为ImageText）。这是我的密码：

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}" Margin="-20,0,-22,0">
    <TextBlock x:Name="TextBlock1" HorizontalAlignment="Left" Margin="130,64,0,0" TextWrapping="Wrap" Text="Load the image here." VerticalAlignment="Top" Height="37" Width="555" FontSize="25"/>
    <Button x:Name="LoadButton" Content="Load" HorizontalAlignment="Left" Margin="50,138,0,0" VerticalAlignment="Top" Height="87" Width="160" FontFamily="Global User Interface" Click="LoadButton_Click"/>
    <Button x:Name="ExtractButton" Content="Extract" HorizontalAlignment="Left" Margin="240,138,0,0" VerticalAlignment="Top" Height="87" Width="160" FontFamily="Global User Interface" Click="ExtractButton_Click"/>
    <Image x:Name="PreviewImage" HorizontalAlignment="Left" Height="296" Margin="76,292,0,0" VerticalAlignment="Top" Width="296"/>
    <TextBlock x:Name="ExtractedTextBlock" HorizontalAlignment="Left" Margin="922,64,0,0" TextWrapping="Wrap" Text="Extracted Text:" VerticalAlignment="Top" FontSize="25" Width="173"/>
    <ScrollViewer>
        <TextBlock x:Name="ImageText" Margin ="922,100,0,0" HorizontalAlignment="Left" TextWrapping="Wrap" Text="Text Not Extracted" VerticalAlignment="Top" Height="427" Width="380"/>
    </ScrollViewer>

但是，当我尝试运行程序时，由于某种原因，所有按钮都不起作用，即我无法单击它们，当我删除ScrollViewer时，一切正常。我做错了什么？提前感谢。

您将边距放在文本块而不是滚动查看器中，请更改为以下内容：

<ScrollViewer Margin ="922,100,0,0" >
    <TextBlock x:Name="ImageText" HorizontalAlignment="Left" TextWrapping="Wrap" Text="Text Not Extracted" VerticalAlignment="Top" Height="427" Width="380"/>
</ScrollViewer>

现在就可以了。无论如何，我鼓励你使用Grid.Rows和Columns或RelativePanel（Windows 10应用程序），而不是像你那样做
