If I understand your problem correctly, you have:

1. Created a UserControl (lets call it MyUserControl).
2. Created a dependency property Orientation for MyUserControl.
3. Within usercontrol you have a stackpanel and you want to bind the Orientation of this stackpanel with Orientation property of MyUserControl.

Try this:

<StackPanel Orientation="{Binding Orientation, 
              RelativeSource={RelativeSource Mode=FindAncestor, 
                                 AncestorType={x:Type MyUserControl }}}">
         <TextBox Name="TValue" Width="40" Height="23" TextChanged="TValue_TextChanged"/>
         <ProgressBar Name="PG1" Width="200" Height="23"/>
</StackPanel> 

Suggestions:

1. Be more explicit while asking for help. You stated a problem (and that too not clearly) and then didn't even mention the question. :)
2. You may want to check if defining a ControlTemplate helps in your scenario.
