Simulating Anchro in WPF Form

1. xmal has <Border><Canvas> multiple sub canvas
2. Each sub-canvas hold different UI
3. Top canvas has SizeChanged event and where we transform button (btn1/2),
   size datagrid (dg) and listbox (lb)

        double dx=0,dy=0;
 private void Canvas_SizeChanged(object sender, SizeChangedEventArgs e)
 {
     this.dg.Width=e.NewSize.Width;
            this.lb.Width = e.NewSize.Width;
            if (e.PreviousSize.Width != 0)
            {
                dx += e.NewSize.Width - e.PreviousSize.Width;
                dy += e.NewSize.Height - e.PreviousSize.Height;
                this.btn1.RenderTransform = new TranslateTransform(dx, dy);
                this.btn2.RenderTransform = new TranslateTransform(dx, dy);
                this.dg.Height += e.NewSize.Height - e.PreviousSize.Height;
            } 
 }
