Xamarin.Forms TabbedPage - Capturing the tab click event (no page change)

Experts,

I was able to extend the Xamarin.Forms TabbedPage class to add an event that is triggered when tabs change – so great.

Now I’d like to be able to capture the tab click event that occurs when someone clicks the tab and the tab does not change (so stays on the current tab).

Can you let me know how this is possible?

Thanks!
