Setting WorldRect of XamGographicMap: No calls to GetTileLayers of custom MapTileSource.
posted

When setting the WorldRect property to

{-20037508,3428;-20037508,3428;40075016,6856;40075016,6856}

Using a custom MapTileSource (that fetches images from a WMS-service). I don't get any calls to GetTileLayers, no images downloaded and no error. Just a mapcontrol without maps in it.

I see that the ActualWorldRect gets immediatly changes its value from {-180;-85,05112878;360;170,10225756} to {-20037508,3428;-90;40075016,6856;NaN}, after setting the WorldRect.

It looks a little suspicious, but It might be because I dont really understand the concept of the ActualWorldRect. I don't see any good description in the documentation. Can someone clarify?

In general, what determines what calls are made to GetTileLayeres?
