I have a source which is:

private ObservableCollection<Tuple<string,WrapPanel>> _list = new ObservableCollection<Tuple<string, WrapPanel>>();

Also I have a Listbox :

<ListBox  SelectionMode="Single"   x:Name="Display" VerticalAlignment="Top"  HorizontalAlignment="Stretch"  MinHeight="100" MinWidth="700" MaxHeight="250"

I set the itemssource from this listboz to my collection source :

Display.ItemsSource = _List;

I would like to display the content of WrapPanels ( Item2) into my listbox. I can not find the way to correctly visualize those wrapPanels obsjects .

I have tried different things in order to visualize those WrapPanels correctly

<!--1-->

 <ListBox  SelectionMode="Single"   x:Name="MFPanelsDisplay" VerticalAlignment="Top"  HorizontalAlignment="Stretch"  MinHeight="100" MinWidth="700" MaxHeight="250"                                       >
 <ListBox.ItemsPanel>

                                        <ItemsPanelTemplate>
                                            <WrapPanel IsItemsHost="True" DataContext="{Binding}"  />
                                        </ItemsPanelTemplate>
                                    </ListBox.ItemsPanel>
</Listbox>

<ListBox  SelectionMode="Single"   x:Name="MFPanelsDisplay" VerticalAlignment="Top"  HorizontalAlignment="Stretch"  MinHeight="100" MinWidth="700" MaxHeight="250" DisplayMemberPath="Item2"/>

</ListBox.ItemTemplate>
                                 <ListBox.ItemTemplate>
                                        <DataTemplate>
                                            <Grid>
                                                <Grid.ColumnDefinitions>
                                                    <ColumnDefinition/>
                                                    <ColumnDefinition/>
                                                </Grid.ColumnDefinitions>
  <WrapPanel Grid.Column="0"  Binding="{Binding Item2}"  />
  <TextBlock Grid.Column="1" Text="{Binding Item1}"/>
                                            </Grid>
                                        </DataTemplate>
                                    </ListBox.ItemTemplate>

The result is always :
System.Windows.Controls.WrapPanel
System.Windows.Controls.WrapPanel
System.Windows.Controls.WrapPanel
System.Windows.Controls.WrapPanel

Any help would be good.
