        <TextBox Height="23" Name="textBox1" Width="Auto" />
        <TextBox Height="23" Name="textBox2" Width="Auto" />

我希望Button填充StackPanel上的所有可用空间。我该怎么做？

如果要填充所有水平和垂直空间，则应使用DockPanel。

    <DockPanel Height="Auto" Name="stackPanel1" Width="Auto" LastChildFill="True">
        <TextBox DockPanel.Dock="Top" Height="23" Name="textBox1" Width="Auto" />
        <TextBox DockPanel.Dock="Top" Height="23" Name="textBox2" Width="Auto" />
        <Button Content="Button" Name="button1" Width="Auto" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" />
    </DockPanel>
