如何让 ListBox 项目填满整个空间？

Question

您好，我看到有很多关于ListBox 的问题，并为DataTemplate 填满了整个空间，但我仍然无法工作。我拥有的是一个 ListBox，DataTemplate 有一个 UserControl。如何让我的 UserControl 拉伸数据以填充空间？

MainWindow XAML sn-p:

<ListBox x:Name="ConfiguredItemsList">
        <ListBox.ItemTemplate>
            <DataTemplate>
                <local:ConfiguredItem DataContext="{Binding}" HorizontalContentAlignment="Stretch" />
            </DataTemplate>
        </ListBox.ItemTemplate>
    </ListBox>

UserControl XAML sn-p:

<UserControl.Resources>
    <local:ImagePathConverter x:Key="ImagePathConverter"/>
</UserControl.Resources>
<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*" />
        <ColumnDefinition Width="75" />
    </Grid.ColumnDefinitions>
    <Grid Grid.Column="0">
        <Grid.RowDefinitions>
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="100" />
            <ColumnDefinition Width="*" />
        </Grid.ColumnDefinitions>

        <TextBlock Grid.Row="0" Grid.Column="0" x:Name="NameLabel" Text="Name:" />
        <TextBlock Grid.Row="0" Grid.Column="1" x:Name="tbName" Text="{Binding Path=Name}" />
        <TextBlock Grid.Row="1" Grid.Column="0" x:Name="DescriptionLabel" Text="Description: " />
        <TextBlock Grid.Row="1" Grid.Column="1" x:Name="Description" Text="{Binding Path=Description}" />
        <TextBlock Grid.Row="2" Grid.Column="0" x:Name="TimeLabel" Text="Time:" />
        <TextBlock Grid.Row="2" Grid.Column="1" x:Name="Time" Text="{Binding Path=ChangeTime, StringFormat={}{0:h:mm tt}}" />            
    </Grid>

    <Border Grid.Column="1" BorderThickness="1" BorderBrush="Black">
        <Image Source="{Binding Path=WallpaperInfo, Converter={StaticResource ImagePathConverter}}" />
    </Border>
</Grid>

您是否尝试将HorizontalContentAlignment 设置为在列表框级别上进行拉伸？

<ListBox x:Name="ConfiguredItemsList"  HorizontalContentAlignment="Stretch">
      <ListBox.ItemTemplate>
            <DataTemplate>
                <local:ConfiguredItem DataContext="{Binding}"/>
            </DataTemplate>
        </ListBox.ItemTemplate>
</ListBox>

注意：我设置了HorizontalContentAlignment 的ListBox 属性，而不是Item。
