silverlight - 为什么 StackPanel 不会在 Silverlight 中将文本 block 放在左侧，将按钮放在右侧？

Question

好吧，我放弃了:我要改成这个堆栈面板 下面，以便它把:

表格最左边的文字

表单最右侧的按钮 .

已下载 Silverlight 3 toolkit它安装了 DockPanel，引用了 System.Windows.Controls，然后遵循 XAML:

<UserControl x:Class="TestData333.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:toolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls"
    Width="400" Height="300">
    <Grid x:Name="LayoutRoot" Background="White">
        <Border CornerRadius="10" Background="Yellow" Padding="20">
            <StackPanel VerticalAlignment="Top" HorizontalAlignment="Left">
                <ScrollViewer Background="Beige" 
                              Height="230"
                              Width="360">
                    <StackPanel>
                        <TextBlock x:Name="TheContent" 
                           Foreground="Navy"
                           FontSize="14"
                           TextWrapping="Wrap"/>
                    </StackPanel>
                </ScrollViewer>

                <toolkit:DockPanel Margin="0 5 0 0">
                    <TextBlock toolkit:DockPanel.Dock="Left" x:Name="ProgressIndicator" Text="Ready..."
                               FontSize="12"
                               HorizontalAlignment="Left"/>
                    <Button toolkit:DockPanel.Dock="Right" Content="Load Data"
                        Width="100"
                        HorizontalAlignment="Right"
                        Click="Button_Load"/>
                </toolkit:DockPanel>

            </StackPanel>
        </Border>
    </Grid>
</UserControl>

您可以使用工具包中的停靠面板或使用带有 2 列的网格。并使第二列的内容右对齐
