A common use case for a FlipView would be to display a list of pictures, say in a photo album. In this photo album you want the ability to zoom in on the pictures.
This can easily be achieved in the WinJS.Binding.Template for the flipview element, simply by having a container div for the image. In the container div's css, set overflow: scrolling and ms-content-zooming: zoom. You can now pinch-to-zoom on
the individual pictures.
However it breaks the "flipping" mechanic of the flipview itself on touch input. Flipping will work, but *only* if the touch motion is perfectly horizontal. This makes it very difficult to build a photo-album type of application using the FlipView.
If any MS employees are here, do you think this is a fixable problem with the FlipView itself or will we need to build custom controls to simulate the photo album behavior?
