Hi Jean-marie,
I cannot reproduce that.
I tested it in the UseDraggableMarkers sample of our HowDoISample. (localhost:53072/Miscellaneous/UseDraggableMarkers/1,AllSamples)
I put this code in UseDraggableMarkers.cshtml:
.CustomOverlays(overlay =>
{
//overlay.InMemoryMarkerOverlay("MarkerOverlay");
overlay.SimpleMarkerOverlay("smo").IsVisible(true).Name("smo").IsBaseOverlay(false).DragMode(MarkerDragMode.Drag).OnClientClick("info").Markers(m =>
{
m.Marker(-8922952.93266, 2984101.58384, new ThinkGeo.MapSuite.MvcEdition.WebImage(21, 25, -10.5f, -25f));
m.Marker(-12454955.13517, 4980025.26614, new ThinkGeo.MapSuite.MvcEdition.WebImage(21, 25, -10.5f, -25f));
m.Marker(-10772117.52067, 3864656.14956, new ThinkGeo.MapSuite.MvcEdition.WebImage(21, 25, -10.5f, -25f));
m.Marker(-13164290.75755, 4035875.09290, new ThinkGeo.MapSuite.MvcEdition.WebImage(21, 25, -10.5f, -25f));
m.Marker(-9754587.80028, 5156136.17929, new ThinkGeo.MapSuite.MvcEdition.WebImage(21, 25, -10.5f, -25f));
});
})
No matter I comment the "overlay.InMemoryMarkerOverlay("MarkerOverlay");" or not, the markers shows on page.
Please let me know if I missed something important.
Any more information or a quickly sample which can reproduce that will be helpful.
Regards,
Don
