Clone ListView and add to exsiting Listview in a Windows 8.1 app

Question

I am trying to copy a ListView and add to an existing ListView (creating a sub-list).  here is my XAML for the ListView:
<ListView x:Name="ListOfTasks" IsItemClickEnabled="False" HorizontalContentAlignment="Stretch" HorizontalAlignment="Stretch" Grid.Column="1" Margin="0,0,0,60" CanReorderItems="True" AllowDrop="True" CanDragItems="True" ItemContainerStyle="{StaticResource ListViewItemStyle2}">
<ListView.ItemTemplate>
<DataTemplate>
<Grid>
<Border Background="{ThemeResource ListViewItemPlaceholderBackgroundThemeBrush}">
</Border>
<TextBlock HorizontalAlignment="Stretch" Margin="5,15,0,15" Text="{Binding Section}" Foreground="{ThemeResource ListViewItemOverlayForegroundThemeBrush}" Style="{StaticResource TitleTextBlockStyle}" TextWrapping="WrapWholeWords" FontSize="18" />
<BitmapIcon x:Name="ShowTasks" Tag="{Binding}" Height="25" Width="25" HorizontalAlignment="Right" VerticalAlignment="Top" Margin="0,10,10,0" UriSource="Assets/CollapseArrow.png" Tapped="ShowTasks_Click" DataContextChanged="ShowTasks_DataContextChanged"/>
<ListView Margin="20,50,0,0" ItemsSource="{Binding Tasks}" Visibility="{Binding showTasks}" HorizontalAlignment="Stretch" CanReorderItems="True" AllowDrop="True" CanDragItems="True" ItemContainerStyle="{StaticResource ListViewItemStyle2}">
<ListView.ItemTemplate>
<DataTemplate>
<Grid>
<Border Background="{ThemeResource ListViewItemPlaceholderBackgroundThemeBrush}">
</Border>
<TextBlock VerticalAlignment="Center" HorizontalAlignment="Stretch" Margin="5,15,0,15" Text="{Binding Task}" Foreground="{ThemeResource ListViewItemOverlayForegroundThemeBrush}" Style="{StaticResource TitleTextBlockStyle}" TextWrapping="WrapWholeWords" FontSize="18" />
<TextBox TextAlignment="Center" MaxHeight="22" VerticalAlignment="Center" Margin="0,0,140,0" HorizontalAlignment="Right" x:Name="TaskPercent" FontSize="18" Text="{Binding Percent}" LostFocus="TaskPercent_LostFocus"/>
<TextBlock VerticalAlignment="Center" Margin="0,0,142,0" HorizontalAlignment="Right" Text="%" FontSize="18" Foreground="Black" />
<Image VerticalAlignment="Center" Height="25" Width="25" Source="{Binding ImagePath}" HorizontalAlignment="Right" Margin="0,0,26,0" Visibility="{Binding Check}"/>
<Button x:Name="details" Tag="{Binding Task}" Content="Details" Click="details_Click" HorizontalAlignment="Right" Margin="0,0,60,0" FontFamily="Global User Interface"/>
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
<ListView Margin="20,100,0,0" ItemsSource="{Binding subSections}" Visibility="{Binding showSubSections}" HorizontalAlignment="Stretch" CanReorderItems="True" AllowDrop="True" CanDragItems="True" ItemContainerStyle="{StaticResource ListViewItemStyle2}">

</ListView>

Answer 1

I figured it out, here is how I did it.
private void ShowSubTasks_Tapped(object sender, TappedRoutedEventArgs e)
var Section = (SectionType)((Windows.UI.Xaml.FrameworkElement)(sender)).Tag;
Grid parent = new Grid();
parent = (Grid)((Windows.UI.Xaml.FrameworkElement)(sender)).Parent;
ListView temp = new ListView();
temp.IsItemClickEnabled = false;
temp.HorizontalAlignment = Windows.UI.Xaml.HorizontalAlignment.Stretch;
temp.HorizontalContentAlignment = Windows.UI.Xaml.HorizontalAlignment.Stretch;
temp.Margin = new Thickness(20, 50, 0, 0);
temp.CanReorderItems = true;
temp.AllowDrop = true;
temp.CanDragItems = true;
temp.ItemContainerStyle = ListOfTasks.ItemContainerStyle;
temp.ItemTemplate = ListOfTasks.ItemTemplate;
temp.Template = ListOfTasks.Template;
temp.Name = "SubSection" + Section.SectionKey;
temp.ItemsSource = Section.subSections;
parent.Children.Add(temp);
