It appears that UICarouselView hasn't supported this feature yet (to use navigation when a UICarouselView item is selected) in the current build version of Crosslight, Crosslight 3 Update 1. But the development team are pleased to add this feature to the roadmap.

This feature has been submitted as feature request. It is filed under CROS-672.
I'll keep this thread updated with any news I heard from the team regarding CROS-672.

Hi Leo,

We have recently released Crosslight 3.0 Update 2 which includes support for navigation in UICarouselView. Please click here to read more about the official press release.

To use navigation in your UICarouselView you can add this code inside your UICarouselView Binding Provider including code for showing the carousel items:

/* To use this template you need to replace the following placeholder:    
 * - TBindingName, use the same Binding Name with Binding Name for showing carousel item 
 * - TDetailViewModel, navigate to target detail view model that you want  
 */
this.AddBinding("TBindingName", BindableProperties.DetailNavigationTargetProperty, new NavigationTarget(typeo(TDetailViewModel)), true);

You can test this code using our View Slider Samples (from git server), try add this code inside ImageSliderBindingProvider.cs at ViewSliderSamples.Core/BindingProviders/ImageSlider/ImageSliderBindingProvider.cs:

this.AddBinding("ViewSlider", BindableProperties.DetailNavigationTargetProperty, new NavigationTarget(typeof(DetailItemSliderViewModel)), true);

Hope that answer your questions :)
