前台XAML代码：

<phone:PhoneApplicationPage 
    x:Class="DemoApp.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
    xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768"
    FontFamily="{StaticResource PhoneFontFamilyNormal}"
    FontSize="{StaticResource PhoneFontSizeNormal}"
    Foreground="{StaticResource PhoneForegroundBrush}"
    SupportedOrientations="Portrait" Orientation="Portrait"
    shell:SystemTray.IsVisible="True" Loaded="PhoneApplicationPage_Loaded">
	<phone:PhoneApplicationPage.Resources>
		
	</phone:PhoneApplicationPage.Resources>

    <!--LayoutRoot is the root grid where all page content is placed-->
    <Grid x:Name="LayoutRoot" Background="Transparent">
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

        <!--TitlePanel contains the name of the application and page title-->
        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
            <TextBlock x:Name="ApplicationTitle" Text="MY APPLICATION" Style="{StaticResource PhoneTextNormalStyle}"/>
            <TextBlock x:Name="PageTitle" Text="page name" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
        </StackPanel>

        <!--ContentPanel - place additional content here-->
        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <ListBox Name="listBox1" VerticalAlignment="Top">
                <ListBox.Template>
                    <ControlTemplate TargetType="ListBox" >
                        <ScrollViewer x:Name="ScrollViewer" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Foreground="{TemplateBinding Foreground}" Padding="{TemplateBinding Padding}">
                            <Grid>
                                <Grid.RowDefinitions>
                                    <RowDefinition></RowDefinition>
                                    <RowDefinition></RowDefinition>
                                </Grid.RowDefinitions>
                                <ItemsPresenter Grid.Row="0"/>
                                <Button Click="Button_Click" Background="Transparent" BorderThickness="0" Content="更多" Grid.Row="1"></Button>
                            </Grid>
                        </ScrollViewer>
                    </ControlTemplate>
                </ListBox.Template>
            </ListBox>
        </Grid>
    </Grid>
 
    <!--Sample code showing usage of ApplicationBar-->
    <!--<phone:PhoneApplicationPage.ApplicationBar>
        <shell:ApplicationBar BackgroundColor="Blue" ForegroundColor="Yellow" IsVisible="True" IsMenuEnabled="True">
            <shell:ApplicationBarIconButton IconUri="/icons/appbar.check.rest.png" Text="Button 1"/>
            <shell:ApplicationBarIconButton IconUri="/icons/appbar.cancel.rest.png" Text="Button 2"/>
        </shell:ApplicationBar>
    </phone:PhoneApplicationPage.ApplicationBar>-->

</phone:PhoneApplicationPage>

后台代码只需在MainPage的构造函数中增添一点代码：

        // Constructor
        public MainPage()
        {
            InitializeComponent();

            // 绑定ListBox的Items
            List<string> list = new List<string>();
            for (int i = 0; i < 50; i++)
            {
                list.Add(i.ToString());
            }
            listBox1.ItemsSource = list;
        }

然后实现一下[更多]按钮的行为：

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            MessageBox.Show("More");
        }
