I'm encountering another little problem.
I'm using the VisualizationLayer with a custom VirtualizationSource (I inherited from IMapItemsVirtualizationSource and I fetch my objects asynchronously from a web service).
Everything works as expected, but I need to know when the objects shown on map change.
For now I use this dirty workaround:
.VisualizationLayer.LayoutUpdated += (s, e) =>
var visibleElements =
There is any event or another approach that I can use?
