Silverlight 5 列表框大小

Question

我在 Star 大小的网格列内和 Listbox DataTemplate 内有一个 Silverlight 5 列表框。

我想要做的是为第二列填充 DataTemplate 网格中的可用空间。如下图所示，它只填充到所包含文本的范围内。

如何让内容填满可用空间？

<ListBox x:Name="TopFaultsListBox" Margin="2" ItemsSource="{Binding TopFaults, Mode=OneWay}" 
            ScrollViewer.HorizontalScrollBarVisibility="Disabled" SelectedIndex="-1" Background="{x:Null}" 
            BorderThickness="5" BorderBrush="#FFB1925C" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" VerticalAlignment="Stretch" VerticalContentAlignment="Stretch" >
    <ListBox.ItemTemplate>
        <DataTemplate>
            <Grid Background="#FFE29826">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto"/>
                    <ColumnDefinition Width="*" />
                </Grid.ColumnDefinitions>
                <Grid.RowDefinitions>
                    <RowDefinition/>
                    <RowDefinition/>
                    <RowDefinition/>
                </Grid.RowDefinitions>
                <TextBlock x:Name="FailureCount" Foreground="Red" FontSize="40" Grid.Row="0" Grid.RowSpan="3" Text="{Binding FaultCount}" Margin="10"/>
                <TextBlock x:Name="AssemblyName" FontSize="20" Text="{Binding AssemblyName}" Grid.Column="1" Grid.Row="1"/>
                <TextBlock x:Name="FaultInformation" FontSize="20" Text="{Binding FaultInformation}" Grid.Column="1" Grid.Row="2"/>
            </Grid>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

您需要在ListBox的ItemContainerStyle中指定HorizontalContentAlignment，并将其设置为Stretch。默认值为左。

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