我不知道WPF应用程序。当文本超出可见区域时，我被分配了一个错误来修复一个简单的问题来添加滚动条。对于第3列，滚动条不可见。另一方面，列4的滚动条。
如何在标记列中添加类似的滚动条？它不允许我发布所有代码，因为它超过了30000个字符的限制。
这是源代码。

试试这个：
如果问题出在第3栏，那可能就在我要在下面显示的内容中
<TextBlock MaxWidth="400"
ScrollViewer.CanContentScroll="True"
ScrollViewer.HorizontalScrollBarVisibility="Auto" >
在这里：（<ListBox Grid.Column="3" Grid.Row="0" .....）
<ListBox Grid.Column="3" Grid.Row="0" ItemsSource="{Binding Source={StaticResource SortedHistoryItems}}">
<!-- <ScrollViewer Panel.ZIndex="1" Margin="-133,-130,0,0" Height="100" Width="300" Visibility="{Binding ShowSearchResults, Converter={StaticResource ResourceKey=boolToVisConverter}}">-->
<ListBox.ItemTemplate>
<DataTemplate DataType="{x:Type m:HistoryLog}">
<WrapPanel>
<TextBlock MaxWidth="400"
ScrollViewer.CanContentScroll="True"
ScrollViewer.HorizontalScrollBarVisibility="Auto">
<TextBlock.Text>
<MultiBinding StringFormat="{}{0}: {1}">
<Binding Path="Type" />
<Binding Path="Oid" />
</MultiBinding>
</TextBlock.Text>
</TextBlock>
<mui:ModernButton Margin="5,0,10,0" EllipseDiameter="16" IconWidth="10" IconHeight="10" EllipseStrokeThickness="1"
IconData="{StaticResource Rightarrow}"

</WrapPanel>
</DataTemplate>
</ListBox.ItemTemplate>
<!-- </ScrollViewer> -->
</ListBox>
解释：对于要显示的ScrollView，必须有一个定义的宽度和高度，因为对于无限大小的对象，不可能有ScrollView。
