Pivot 控件 我们常常在设置的界面看到。非常方便，能争强用户的体验性。

Pivot最方便的用法 是创建项目的时候 直接按选中 Pivot项目

这样我们直接创建完成项目后就能看见 ，一个已经填充数据的默认页。

默认页的代码如下

<phone:PhoneApplicationPage
    x:Class="PhoneApp10.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:DataContext="{d:DesignData SampleData/MainViewModelSampleData.xaml}"
    FontFamily="{StaticResource PhoneFontFamilyNormal}"
    FontSize="{StaticResource PhoneFontSizeNormal}"
    Foreground="{StaticResource PhoneForegroundBrush}"
    SupportedOrientations="Portrait"  Orientation="Portrait"
    shell:SystemTray.IsVisible="True">

    <!--LayoutRoot is the root grid where all page content is placed-->
    <Grid x:Name="LayoutRoot" Background="Transparent">

       

        <!--Pivot Control-->
        <phone:Pivot Title="MY APPLICATION">
            <!--Pivot item one-->
            <phone:PivotItem Header="first">
                <!--Double line list with text wrapping-->
                <phone:LongListSelector Margin="0,0,-12,0" ItemsSource="{Binding Items}">
                    <phone:LongListSelector.ItemTemplate>
                        <DataTemplate>
                            <StackPanel Margin="0,0,0,17">
                                <TextBlock Text="{Binding LineOne}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
                                <TextBlock Text="{Binding LineTwo}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
                            </StackPanel>
                        </DataTemplate>
                    </phone:LongListSelector.ItemTemplate>
                </phone:LongListSelector>
            </phone:PivotItem>

            <!--Pivot item two-->
            <phone:PivotItem Header="second">
                <!--Double line list no text wrapping-->
                <phone:LongListSelector Margin="0,0,-12,0" ItemsSource="{Binding Items}">
                    <phone:LongListSelector.ItemTemplate>
                            <DataTemplate>
                                <StackPanel Margin="0,0,0,17">
                                    <TextBlock Text="{Binding LineOne}" TextWrapping="NoWrap" Margin="12,0,0,0" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
                                    <TextBlock Text="{Binding LineThree}" TextWrapping="NoWrap" Margin="12,-6,0,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
                                </StackPanel>
                            </DataTemplate>
                    </phone:LongListSelector.ItemTemplate>
                </phone:LongListSelector>
            </phone:PivotItem>
        </phone:Pivot>

        <!--Uncomment to see an alignment grid to help ensure your controls are
            aligned on common boundaries.  The image has a top margin of -32px to
            account for the System Tray. Set this to 0 (or remove the margin altogether)
            if the System Tray is hidden.

            Before shipping remove this XAML and the image itself.-->
        <!--<Image Source="/Assets/AlignmentGrid.png" VerticalAlignment="Top" Height="800" Width="480" Margin="0,-32,0,0" Grid.Row="0" IsHitTestVisible="False" />-->
    </Grid>

</phone:PhoneApplicationPage>

OK 这是完整页的代码。

接着我们将 内容页的代码页粘贴出来

代码如下

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

            // Set the data context of the listbox control to the sample data
            DataContext = App.ViewModel;

            // Sample code to localize the ApplicationBar
            //BuildLocalizedApplicationBar();
        }

        // Load data for the ViewModel Items
        protected override void OnNavigatedTo(NavigationEventArgs e)
        {
            if (!App.ViewModel.IsDataLoaded)
            {
                App.ViewModel.LoadData();
            }
        }

我们在 xaml 页 看到这句话 

d:DataContext="{d:DesignData SampleData/MainViewModelSampleData.xaml}"

引入了个外部 的数据源对应文件如图

文件中的 内容如下

<vm:MainViewModel
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:vm="clr-namespace:PhoneApp10.ViewModels"
    SampleProperty="Sample Text Property Value">

    <vm:MainViewModel.Items>
        <vm:ItemViewModel LineOne="design one" LineTwo="Maecenas praesent accumsan bibendum" LineThree="Maecenas praesent accumsan bibendum dictumst eleifend facilisi faucibus habitant inceptos interdum lobortis nascetur"/>
        <vm:ItemViewModel LineOne="design two" LineTwo="Dictumst eleifend facilisi faucibus" LineThree="Pharetra placerat pulvinar sagittis senectus sociosqu suscipit torquent ultrices vehicula volutpat maecenas praesent"/>
        <vm:ItemViewModel LineOne="design three" LineTwo="Habitant inceptos interdum lobortis" LineThree="Accumsan bibendum dictumst eleifend facilisi faucibus habitant inceptos interdum lobortis nascetur pharetra placerat"/>
        <vm:ItemViewModel LineOne="design four" LineTwo="Nascetur pharetra placerat pulvinar" LineThree="Pulvinar sagittis senectus sociosqu suscipit torquent ultrices vehicula volutpat maecenas praesent accumsan bibendum"/>
        <vm:ItemViewModel LineOne="design five" LineTwo="Sagittis senectus sociosqu suscipit" LineThree="Dictumst eleifend facilisi faucibus habitant inceptos interdum lobortis nascetur pharetra placerat pulvinar sagittis"/>
        <vm:ItemViewModel LineOne="design six" LineTwo="Torquent ultrices vehicula volutpat" LineThree="Senectus sociosqu suscipit torquent ultrices vehicula volutpat maecenas praesent accumsan bibendum dictumst eleifend"/>
    </vm:MainViewModel.Items>

</vm:MainViewModel>

OK 

我们看到 预览的窗口效果如下图

当我们启动模拟器就能看到Pivot控件的效果了。

上面数据绑定的内容可以换成其他数据可以直接写入。

因为直接创建就有了。所以不附加源码了。

OK 基本上就这多。

(写的不好请见谅，有不对请留言告知我，免得误人子弟。）
