<ListView                        ItemsSource="{Binding}"                        IsItemClickEnabled="True"                        ItemClick="GroupSection_ItemClick"                        ContinuumNavigationTransitionInfo.ExitElementContainer="True">                        <ListView.ItemTemplate>                            <DataTemplate>                                <StackPanel Margin="0,0,0,27.5">                                    <TextBlock Text="{Binding Title}" Style="{ThemeResource ListViewItemTextBlockStyle}" />                                </StackPanel>                            </DataTemplate>                        </ListView.ItemTemplate>                    </ListView>

{Binding MyObject.MyProperty} - bind to the specific property of MyObject

  mc:Ignorable="d"    DataContext="{Binding DefaultViewModel.Item, RelativeSource={RelativeSource Self}}"    d:DataContext="{Binding Groups[0].Items[0], Source={d:DesignData Source=/DataModel/SampleData.json, Type=data:SampleDataSource}}"
