Is there a way to determine when the map is finished rendering? there was a post in 2015 saying it was coming out soon, but I can't find any mention of it in the API reference or any kind of search
Look for the DrawStatusChanged event in MapView.
In your handler check the Status property in the DrawStatusChangedEventArgs parameter for DrawStatus.Completed.
Thank you, that was what I was looking for
Retrieving data ...
