I've tried it a few different ways and the panning operation still completes when setting IMapPanEventArgs.Cancel to true. I assume that it should not perform the actual pan and leave the map where it is.
I have tried this in both Chrome and Safari, latest versions.
My ultimate goal is to be able to restrict viewing of the map to only a certain range of Lat/Long values, maybe there is another way to accomplish this goal?
