I normally just have regular content pages and I when loading something, I put an overlay on top, generally to stop them doing anything else, with an activity indicator and loading text.
However when I go into a Tabbed Page, my Content Page is just a section of the tabbed page and can't overlay the entire page.
I can't put anything in the TabbedPage, except just child pages, that I can find anyway, ideally that is where it would go.
Does anyone have any ideas? Or is my design with the overlay a flawed approach?
