I have a WPF application that uses touch events (TouchDown, TouchMove, TouchUp). Everything works fine. But if I give the ViewportLayout (Eyeshot 11) component somewhere to the application, the touch events will stop working in the whole of application. Does anyone know why? Thank you very much.

  • You seem to have a focus issue. use a connected mouse to click something else and then try the touch again does it work ? – Franck Jan 08 '19 at 15:00
  • No, it still doesn't work. If I put a touch event to the window of sample example (for example 'Arrows'), the application behaves the same way. The touch event is not triggered. I have to remove the viewportlayout component to trigger the touch events. – user3489644 Jan 09 '19 at 07:02
  • Window in the example 'Arrows' has FocusManager.FocusedElement="{Binding ElementName=viewportLayout1}". If I delete this property, touch event still doesn't work. I do not set this property anywhere in my application. – user3489644 Jan 09 '19 at 07:19
