@terreb i don't if you can access to $parents from a view loaded with builder. I will do my tests later on and let you know. Thanks

You can follow this https://github.com/NativeScript/NativeScript/issues/3077

{N} Team provided an example for this that i will be testing. Thanks

It seems that $parents doesn't provide access to the native widget properties but it's binding context instead, so if you want to access the CarouselView properties, you have to expose them in the ViewModel like this:

get position(): number {
   var page = frame.topmost().currentPage;
    var slider = <CarouselView>page.getViewById("carouselView");
    return slider.position;
}
