我有一个 wpf 应用程序。在窗口中，我有一个 TextBlock，其中包含很多数字，每个数字都在其行中。我希望滚动查看器在需要时出现。它不起作用...这是代码

<ScrollViewer CanContentScroll="True" Margin="5,25,5,0" Grid.Row="2" HorizontalScrollBarVisibility="Auto" >
                 <TextBlock MaxHeight="500" Height="Auto" Width="Auto" VerticalAlignment="Top" Name="TextBlock_Results"/>
        </ScrollViewer>

默认情况下，滚动查看器中的文本块无法滚动。要使 ScrollViewer 能够执行基于像素的滚动，您需要将 can 内容滚动设置为 false。

两个滚动条的可见性是独立控制的。我已将垂直滚动条隐藏在下面的一个中。

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
<Grid>
    <ScrollViewer CanContentScroll="False" Margin="5,25,5,0" Grid.Row="2" HorizontalScrollBarVisibility="Auto"  VerticalScrollBarVisibility="Hidden">
        <TextBlock MaxHeight="500" Height="Auto" Width="Auto" VerticalAlignment="Top" Name="TextBlock_Results"
                  Text="a"/>
    </ScrollViewer>

</Grid>

The text block in the scroll viewer is not capable of scrolling by default. To enable the ScrollViewer to perform pixel based scrolling you need to set the can content scroll to false.

The visibillity of the two scroll bars are controlled independently. I have hidden the vertical scroll bar in the one bellow.

<Window x:Class="WpfApplication1.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
<Grid>
    <ScrollViewer CanContentScroll="False" Margin="5,25,5,0" Grid.Row="2" HorizontalScrollBarVisibility="Auto"  VerticalScrollBarVisibility="Hidden">
        <TextBlock MaxHeight="500" Height="Auto" Width="Auto" VerticalAlignment="Top" Name="TextBlock_Results"
                  Text="a"/>
    </ScrollViewer>

</Grid>
