ComboBox Whith a TreeView - wpf

Question

I need to create a userControl like a Combobox.
In the items in need a TreeView and a Button.
If I navigate the Tree the Item should go to the Text Box in the Bottom.
If I click the Button the Tree should Collapsed.
My First idea was like This but it isn't good.
<StackPanel Orientation="Vertical">
<StackPanel Orientation="Horizontal">
<TextBox Text="{Binding Adresse, Mode=TwoWay}" MaxLength="50" MinWidth="170" Grid.Row="5" Margin="5,2,5,2"/>
<Button Width="25" Margin="2" Click="Down">
<Image Source="/C1_net;component/Images/arrow.jpg" HorizontalAlignment="Left" />
</Button>
</StackPanel>
<StackPanel x:Name="Tree" Orientation="Vertical" Visibility="Collapsed">
<sdk:TreeView Height="200" Name="treeView1" Width="200" />
<Button Content="{Binding Path=ApplicationStrings.OKButton, Source={StaticResource ResourceWrapper}}" Width="75" Margin="5" Click="OnOk" HorizontalAlignment="Right"/>
</StackPanel>
</StackPanel>
</Grid>
If I switch to Visible the Control needs more space.
So I need to bring the Tree in Front of the Rest of the Window.
Any ideas?

Ok.
I think you should revisit your interaction.
my problemm wase to think if i select i Item, The Tree wood be closed.
I will navigate in a Hirarchical DataObjekt and Put the Path as selectet Item.
So now I will to somting like this:
public interface ITreeViewItemModel
{
string SelectedValuePath { get; }
bool IsExpanded { get; set; }
bool IsSelected { get; set; }
IEnumerable<ITreeViewItemModel> GetHierarchy();
IEnumerable<string> GetDisplayHierarchy();
IEnumerable<ITreeViewItemModel> GetChildren();
}
and.
public class ComboBoxTreeView : ComboBox
{
private ExtendedTreeView _treeView;
private ContentPresenter _contentPresenter;
public ComboBoxTreeView()
{
this.DefaultStyleKey = typeof(ComboBoxTreeView);
}
......
