WPF - touch gestures - depressed mouse click if scrolling

Question

I have several videos in ScrollViewer, and when I click on one of these videos, it plays, and I have a movie in full screen, and I moved with the scroll bar. He moves with the video. This is normal. I implemented this by adding a click on the multimedia element, and now I am testing this on the touch screen and it works.

But I want to distinguish between a click on a video and a movement in this area. This user does not want to “select” the video, but he simply moves with the area, but not in the scroll bar, but in the area with the video. For a better understanding, I added an image:

So that WPF makes the difference between click and movement (to have both, but still only one calling). What is the best way to do this? Thanks

It is very difficult to handle touch events yourself, especially when you have to process nested controls.

I think the easiest way to solve this problem is to use the Microsoft Surface Touch Pack

Replace ScrollView with SurfaceScrollView and place a transparent SurfaceButton over your MediaElements and respond to the Click event (or handle it with the a command).

Thus, Microsoft does complex panning (scrolling) or clicking (clicking) for you. And as a pleasant side effect, you get it for free, like bouncing and interfering with ScrollViewer.
