Create ListView ItemTemplate programmatically/dynamically

Question

Hi,
here is my problem:
I have a ListView control on my xaml page. But the data item structure is different from on item to another. Sometimes i need a Grid with 4 columns, sometimes with 5, sometimes with 6. So my idea was to dynamically create the data template and change the
ColumnDefinitions programmatically . But i don´t find a way to do it. I come from the HTML/JS Windows App Devolpment side, and there it is relatively easy to do such things ...

try this:
<Grid>
<ListView x:Name="listview">
<ListView.ItemContainerStyle >
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemTemplate >
<DataTemplate >
<StackPanel >
<TextBlock Text="{Binding GroupName}"/>
<ListView ItemsSource="{Binding Items}" Background="Blue" >
<ListView.ItemsPanel >
<ItemsPanelTemplate>
<WrapGrid Orientation="Vertical" MaximumRowsOrColumns="1"/>
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.ItemTemplate >
<DataTemplate >
<Border BorderBrush="Yellow" BorderThickness="2" Width="24" >
<TextBlock Text="{Binding Data}" FontSize="18" Foreground="White" />
</Border>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</StackPanel>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
</Grid>
namespace App1
/// <summary>
/// An empty page that can be used on its own or navigated to within a Frame.
/// </summary>
public sealed partial class MainPage : Page
public MainPage()
this.InitializeComponent();

protected override void OnNavigatedTo(NavigationEventArgs e)
var d =BuildTestData();
listview.ItemsSource = d;
foreach (var item in d)
Debug.WriteLine(item.GroupName);
private List<MyGroup> BuildTestData()
List<MyGroup> groups = new List<MyGroup>();
List<Detail> c1 = new List<Detail>();

c1.Add(new Detail() { Data = "2" });
c1.Add(new Detail() { Data = "3" });

List<Detail> c2 = new List<Detail>();
c2.Add(new Detail() { Data = "11" });

return groups;
public class MyGroup
public List<Detail> Items
{ get; set; }
public string GroupName

public string Data
get;
set;
