I have 3 Views:
1) Navigation-View with 2 Buttons to jump from View 2 to View 3 (This view is permanent visible)
If the user is on view 2 and clicks on Button "view_3" I have a to do some checks for the values in view 2. If an error occurs, I dont want to navigate to view_3.
How can I cancel the navigation?
Thanks a lot, Regards Mario
