In this article we are going to see how to create a sample windows phone pivot application, for our sample we are consider to display some information related to social network, but this is only a sample so data are created in view model collection and directly bind to the View.

so now we can see how to create a sample app.

Output: sample screen

 


xaml:
Styles are defined in one place and create a data template from the code bind the data to the view.

    <!--LayoutRoot is the root grid where all page content is placed-->
    <Grid x:Name="LayoutRoot" Background="Transparent">
        <!--Pivot Control-->
        <phone:Pivot Title="{Binding LocalizedResources.AppName,Source={StaticResource LocalizedStrings}}">
            <!--Pivot item one-->
            <phone:PivotItem Header="{Binding LocalizedResources.Facebook,Source={StaticResource LocalizedStrings}}">
                <!--Double line list with text wrapping-->
                <phone:LongListSelector Margin="0,0,-12,0" ItemsSource="{Binding FacebookData}">
                    <phone:LongListSelector.ItemTemplate>
                        <DataTemplate>
                            <StackPanel Margin="0,0,0,17">
                                <StackPanel Orientation="Horizontal">
                                    <Border BorderBrush="PowderBlue" Background="PowderBlue" CornerRadius="5" Margin="3">
                                       <Image Margin="4" Source="{Binding Image}" Stretch="UniformToFill" Width="100" Height="100" />
                                    </Border>
                                    <StackPanel Orientation="Vertical">
                                        <TextBlock FontSize="30" Foreground="CornflowerBlue" FontWeight="Medium" Text="{Binding UserName}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}"/>
                                        <TextBlock TextTrimming="WordEllipsis" MaxWidth="300" Text="{Binding About}"  TextWrapping="Wrap" Height="70"
                                                   Margin="3"/>
                                    </StackPanel>                                  
                                </StackPanel>                               
                            </StackPanel>
                        </DataTemplate>
                    </phone:LongListSelector.ItemTemplate>
                </phone:LongListSelector>
            </phone:PivotItem>

            <!--Pivot item two-->
            <phone:PivotItem Header="{Binding LocalizedResources.Google,Source={StaticResource LocalizedStrings}}">
                <phone:LongListSelector Margin="0,0,-12,0" ItemsSource="{Binding GoogleData}">
                    <phone:LongListSelector.ItemTemplate>
                            <DataTemplate>
                            <StackPanel Margin="0,0,0,17">
                                <StackPanel Orientation="Horizontal">
                                    <Border BorderBrush="Yellow" Background="OrangeRed" CornerRadius="5" Margin="3">
                                        <Image Margin="4" Source="{Binding Image}" Stretch="UniformToFill" Width="100" Height="100" />
                                    </Border>
                                    <TextBlock TextTrimming="WordEllipsis" MaxWidth="300" Text="{Binding About}"  TextWrapping="Wrap" Height="70"
                                                   Margin="3"/>
                                </StackPanel>
                                <TextBlock FontSize="30" Foreground="Orange" FontWeight="Medium"
                                           Text="{Binding UserName}" TextWrapping="Wrap"
                                           Style="{StaticResource PhoneTextExtraLargeStyle}"/>
                              
                            </StackPanel>
                        </DataTemplate>
                    </phone:LongListSelector.ItemTemplate>
                </phone:LongListSelector>
            </phone:PivotItem>
    
        </phone:Pivot>    

    </Grid>




C#:
        public MainPage()
        {
            InitializeComponent();
            SocialNetworkData data = new SocialNetworkData();
            DataContext = data;
        }




Model Class
    Model class which have google+ and Facebook sample model data to bind to the view which follows the MVVM pattern.
