Help with WPF Binding - wpf

Question

I need to bind the custom dependency property to the Image elements inside a control.
Now the Label's Foreground binds very well to TextForeground, but not the GeometryDrawing inside the Image (the Image remains Transparent).
What is wrong?

Answer 1

GeometryDrawing does not have a TextForeground property. You are referencing Self, which would be the GeometryDrawing. Change your RelativeSource if you are trying to grab the TextForeground from a different Control.
<GeometryDrawing.Pen>
<Pen Brush="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}, Path=TextForeground}" Thickness="1"/>
</GeometryDrawing.Pen>

Answer 2

<UserControl x:Name="MyStopControl" >
...
<Pen Brush="{Binding ElementName=MyStopControl, Path=TextForeground}"/>
...
</UserControl>
