margin

I'd like the Margin property to reference the center of the UIElement and not the top-left corner. That way when I change the width/height of the UIElement it stays in the same spot.

Is there a way to configure this behavior or I'll have to rely on Binding to make the adjustment ?

Thanks.

For instance if I change the Width/Height of the following rectangle, its center will move.

<Grid>
    <Rectangle Fill="#FF991C1C" Width="10" Height="40" HorizontalAlignment="Left" Margin="90,161,0,0" VerticalAlignment="Top"/>
</Grid>
