I implemented a subclass of ImageTiledLayer.
if I check cancellationToken.IsCancellationRequested == true and throw OperationCanceledException or TaskCanceledException with loading operation cancel, the method GetTileDataAsync will never be called with same level, row and column parameters. I guess that wrong result is cached.

How is the right way to use cancellationToken?

Hi,

Can you share your code for your ImageTiledLayer subclass and the code that calls it?

Thanks

Hi,

Thank you for your reply. My subclass has a lot of code which reading and some processing of geotiff files. I can make a simple project with this problem but only later, maybe after a couple of weeks

Thanks
