        base.OnElementChanged(e);

        //if we have a new forms element, we want to update text with font style (as specified in forms-pcl) on native control
        if (e.NewElement != null)
            UpdateTextOnControl();
    }

    protected override void OnElementPropertyChanged(object sender, PropertyChangedEventArgs e)
    {
        base.OnElementPropertyChanged(sender, …
