wpf - 在网格列内制作一个 TextBlock 换行

Question

我有以下 XAML，它在网格中显示一个文本 block 。问题是它只是拉伸(stretch)开来，它甚至拉伸(stretch)得比 window 的宽度还大。

<Grid Background="Gray">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="Auto" />
    </Grid.RowDefinitions>

    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" />
        <ColumnDefinition Width="Auto" />
    </Grid.ColumnDefinitions>

    <Label Grid.Row="1" Grid.Column="0" Padding="0" FontWeight="Bold" Margin="0,0,5,0">Description:</Label>
    <TextBlock Grid.Row="1" Grid.Column="1" Text="{Binding Description}" TextWrapping="Wrap" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" />
</Grid>

Answer 1

您需要 restrict the width使文本换行的第二列 -

<Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto" />
        <ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
