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");

        }
