Description Ray Kelly 2017-11-20 17:26:45 UTC
When using a ListView and BeginRefresh/EndRefresh, the pinch zoom dots appear for an instant on each ListView update.   You can see the behavior in this video:

This has been around since XF 2.3.6.

This does in fact appear to occur -- tested against a Nougat emulator. A basic ListView calling BeginRefresh seems to do the trick.
Comment 2 adrianknight89 2017-12-09 05:15:18 UTC
Isn't BeginRefresh supposed to show the pull-to-refresh icon? Are you using an ObservableCollection for your listview ItemsSource?
Comment 3 Ray Kelly 2017-12-12 18:42:41 UTC
It isn't showing the pull to refresh icon.  Did you watch the video?
