如何在 textBlock 工作中换行

Question

我的 TextBlock 似乎无法换行。

TextWrapping="Wrap" 不起作用。此外，诸如 TextTrimming 之类的任何其他内容都不会影响我的 TextBlock。我假设其他控件正在阻塞？谈论"txtErrorLabel"

<Window x:Class="BLVKServiceDashboard.Pages.ErrorWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="ErrorWindow" Height="555" Width="420" Icon="/BLVKServiceDashboard;component/error.ico" ResizeMode="NoResize" WindowStartupLocation="Manual" ShowInTaskbar="False" Background="#FFEEEEEE" WindowStyle="None">

    <ListBox x:Name="lstErrorItems" ScrollViewer.VerticalScrollBarVisibility="Auto" BorderThickness="0" Background="{x:Null}" Margin="0,58" ScrollViewer.HorizontalScrollBarVisibility="Disabled">

            <DataTemplate>
                <Grid Width="500" Height="38" Margin="0,0,0,0">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="380"/>
                        <ColumnDefinition Width="120"/>
                    </Grid.ColumnDefinitions>
                    <ScrollViewer Grid.ColumnSpan="2">
                        <StackPanel Orientation="Horizontal">
                            <TextBlock Foreground="Black" Text="Fehler: " HorizontalAlignment="Left" Height="Auto" Width="Auto" VerticalAlignment="Top"  Margin="5,10,0,2" FontSize="14" FontFamily="Segoe UI" ScrollViewer.VerticalScrollBarVisibility="Disabled"/>
                            <TextBlock x:Name="txtErrorLabel" Foreground="Black" Text="{Binding}" HorizontalAlignment="Left" Height="Auto" VerticalAlignment="Top" Margin="5,10,0,2" FontSize="14" FontFamily="Segoe UI"/>
                        </StackPanel>
                    </ScrollViewer>
                </Grid>
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>
    <Button x:Name="btnDelete" Content="Meldungen löschen" Margin="147,514,147,0" VerticalAlignment="Top" Width="122" Click="btnDelete_Click" HorizontalContentAlignment="Center" RenderTransformOrigin="0.467,0.909"/>
</Grid>

Answer 1

您的文本块位于 stackPanel 中，它没有为您的文本块提供边界。

将父级更改为为您的文本块提供边界的东西或为堆栈面板本身设置限制。

TextWrapping只有在文本块超过父控件的宽度时才会生效。但是 stackPanel 从不对其子项强加任何边界，因此所有 space 都可用。

一个可能的解决方案是——

<Grid Width="500" Height="Auto" Margin="0,0,0,0">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="380"/>
            <ColumnDefinition Width="120"/>
        </Grid.ColumnDefinitions>
        <ScrollViewer Grid.ColumnSpan="2">
            <Grid >
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto"/>
                    <ColumnDefinition Width="*"/>
                </Grid.ColumnDefinitions>
                <TextBlock Foreground="Black" Text="Fehler: " HorizontalAlignment="Left" Height="Auto" Width="Auto" VerticalAlignment="Top"  Margin="5,10,0,2" FontSize="14" FontFamily="Segoe UI" ScrollViewer.VerticalScrollBarVisibility="Disabled"/>
                <TextBlock Grid.Column="1" x:Name="txtErrorLabel" 
                           Foreground="Black" 
                           TextWrapping="Wrap"
                           Text="123456789123456789123456789123456789123456789123456789123456789123456789123456789123456789" 
                           HorizontalAlignment="Left" 
                           VerticalAlignment="Top" 
                           Margin="5,10,0,2" 
                           FontSize="14" FontFamily="Segoe UI"/>
            </Grid>
        </ScrollViewer>
    </Grid>
