C# Wpf surfaceusercontrol Contact Events not firing

Question

I have a SurfaceWindow . In it is a Scatterview with a ScatterViewItem and in the Scatterviewitem is a viewbox which contains the SurfaceUserControl . I added some ContactEvents to the control like ContactDown , Contactup , ContactTapGesture , etc (and the Preview versions of the events).

The only events fired are contactdown and leave. On the Scatterviewitem the other events work too.

Someone know why?

Sorry that i cant show you any code. I'm on work and for some reason the proxy is blocking the login to this site. I'm writing this with my phone.

                            <uc:MainMap PreviewContactTapGesture="MainMap_PreviewContactTapGesture" ContactTapGesture="MainMap_ContactTapGesture"></uc:MainMap>
                        </Viewbox>
                    </ControlTemplate>
                </s:ScatterViewItem.Template>
            </s:ScatterViewItem>
        </s:ScatterView>
    </Grid>
</s:SurfaceWindow>

This is my Surfacewindow Code. The PreviewContactTapGesture and ContactTapGesture events on MainMap work only if they arent in the Scatterviewitem.

Thanks
