Here is our code using the Google Maps Subgurim
GInfoWindow window1 = new GInfoWindow(icon1, "bin 1", false, Glistener.Event.mouseover);
GMap1.Add(window1);
GInfoWindow window2 = new GInfoWindow(icon1, "bin 2", false, Glistener.Event.mouseover)
GMap1.Add(window2);
and what we want to do is that the infowindow of both markers are always open instead of hovering the mouse on the marker? Is that possible?
