Hi,
If you want to Draw a shape on map or measure distance between different part of map you need to assign new instance of TrackInteractiveOverlay to TrackOverlay.
after this assignment if we just refresh TrackOverlay map does not work fine(map panning with mouse) and we need to refresh entire map .
obviously if we have loaded big shapefile, refreshing whole map take long time, How I can Solbe this issue?
I create simple appliction, that show this problem.in the sample application, we have two buttons for going to Draw mode(one refresh whole map, one just refresh Trackoverlay)
Regards,
Ben
