WPF XAML ListView - 使TextBlock文本换行

Question

我有一个像ListView.ItemTemplate这样的ListView

<ListView
    x:Name="myList" 
    BorderBrush="Transparent"
    ItemsSource="{Binding MyItems}" 
    SelectedIndex="0"
    ScrollViewer.CanContentScroll="True"
    ScrollViewer.VerticalScrollBarVisibility="Auto">

    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
            <Setter Property="Padding" Value="0" />
        </Style>
    </ListView.ItemContainerStyle>

    <ListView.ItemTemplate>
        <DataTemplate>
            <Grid Margin="5,5,5,5">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="200"/> <--THIS WILL FORCE WRAPPING
                    <ColumnDefinition Width="50"/>
                </Grid.ColumnDefinitions>
                <Grid>
                    <Grid.RowDefinitions>
                        <RowDefinition Height="*"/>
                        <RowDefinition Height="*"/>
                    </Grid.RowDefinitions>

                    <TextBlock Text="{Binding FilePath}" 
                               Grid.Row="0" Margin="3,3,3,3" 
                               Style="{StaticResource MyFilePathTextLabel}" 
                               TextWrapping="WrapWithOverflow"/>   <-- THIS WILL NOT WRAP TEXT
                    <StackPanel Orientation="Horizontal" Grid.Row="1" Margin="3,3,3,3">
                        <TextBlock Text="Lab location: "/>
                        <TextBlock Text="{Binding LabLocation}" 
                                   Style="{StaticResource MyLabLocationTextLabel}"/>
                    </StackPanel>
                    ...
                    ...
        </DataTemplate>
    </ListView.ItemTemplate>
    ...
    ...
</ListView>

这将显示如下ListView项:

----------------------------------
C:/samples/folderA/myfile1.txt     <-- NO WRAP AS IT FITS
Lab location: Chemistry Lab 301
----------------------------------
C:/samples/folderA/folderB/fold
erC/folderD/folderE/folderF/myf
ile2.txt                           <-- WRAP SINCE NOT FITTING
Lab location: Chemistry Lab 301
----------------------------------
C:/samples/folderA/folderB/myfi
le3.txt                            <-- WRAP SINCE NOT FITTING
Lab location: Chemistry Lab 301
----------------------------------
C:/samples/folderA/folderB/fold
erC/folderD/folderE/folderF/fol
derG/folderH/folderI/folderJ/fo
lderK/myfile4.txt                  <-- WRAP SINCE NOT FITTING
Lab location: Chemistry Lab 301
----------------------------------
C:/samples/myfile5.txt             <-- NO WRAP AS IT FITS
Lab location: Chemistry Lab 301
----------------------------------

在上面,如果文件位置不适合ListView的宽度,则每个项目都显示文件位置.

更新: 更新了XAML

更新2: 将网格容器的列宽设置为硬编码值将强制换行(参见上面的注释行).但由于表单可以调整大小,因此网格和ListView也可以调整大小.因此,我不能硬编码宽度. 它需要根据表单的当前大小进行换行.

设置HorizontalContentAlignement="Stretch"ListView对象本身以告诉它水平拉伸它的内容以适应可用空间,并将其设置HorizontalScrollBarVisiblilty为Disabled以确保禁用水平滚动.

<ListView x:Name="myList" ...
          HorizontalContentAlignment="Stretch"
          ScrollViewer.HorizontalScrollBarVisibility="Disabled">
