[WPF]如何设置数据模板中网格的宽度和高度

Question

有以下wpf代码：

<Window x:Class="WpfApplication5.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:c="clr-namespace:WpfApplication5"
Title="Window1" Height="300" Width="300">
<Window.Resources>
    <c:Places x:Key="PlacesData"/>
    <DataTemplate x:Key="DataTemplate" DataType="{x:Type c:Place}">
        <Grid HorizontalAlignment="Left" 
              >
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="*" />
                <ColumnDefinition Width="40"/>
            </Grid.ColumnDefinitions>
            <TextBlock Grid.Column="0" Text="{Binding Name}"/>
            <TextBlock Grid.Column="1" Text="{Binding State}" TextAlignment="Right"/>
        </Grid>
    </DataTemplate>
</Window.Resources>
<Grid>
    <ListBox ItemsSource="{Binding Source={StaticResource PlacesData}}" 
             ItemTemplate="{StaticResource DataTemplate}"
             ScrollViewer.HorizontalScrollBarVisibility="Disabled"  
             ScrollViewer.CanContentScroll="False"
             HorizontalContentAlignment="Stretch"/>
</Grid>

输出是这样的

我希望状态代码始终显示在列表框的右侧，如果我调整窗口大小，也必须发生这种情况。

有什么想法吗？

Answer 1

确保每个 ListBoxItem 的 Horizo​​ntalContentAlignment 设置为 Stretch：

<ListBox>
    <ListBox.ItemContainerStyle>
        <Style TargetType="ListBoxItem">
            <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
        </Style>
    </ListBox.ItemContainerStyle>
</ListBox>

Answer 2

使网格的Horizo​​ntalAlignment Stretch，而不是Left。

<DataTemplate x:Key="DataTemplate" DataType="{x:Type c:Place}">
    <Grid HorizontalAlignment="Stretch">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*" />
            <ColumnDefinition Width="40"/>
        </Grid.ColumnDefinitions>
        <TextBlock Grid.Column="0" Text="{Binding Name}"/>
        <TextBlock Grid.Column="1" Text="{Binding State}" TextAlignment="Right"/>
    </Grid>
</DataTemplate>
