问题
In most windows 8 apps when you tap anywhere inside the app you see a white-circle tap notification. For some reason, the notification doesn't occur in my app. How is the indication enabled or disabled?
i tried IsHitTestVisible , but don't see anything change in my grouped item page.
回答1:
IsHitTestVisible has nothing to do with the white-gray tap short-animation, which is a shell feature. All apps are showing it when a touch event occurs in the context of the OS.

This question is kinda related to my lastest question so I will leave the answer here if someone tries to solve the same issue.
You can disable/enable the visual tap feedback with:
PointerVisualizationSettings.GetForCurrentView().IsContactFeedbackEnabled = false;
You can also remove it forever in your control panel.
