marker doesn't appear on the gMap

Hi all
I tried to put marker on map - but it didn't appear there ((

private GMapOverlay _gMapLayerTop;

_gMapLayerTop = new GMapOverlay(gMapControl1, "top");

private void gMapControl1_MouseUp(object sender, MouseEventArgs e)
                if(e.Button == MouseButtons.Left)
                    var gP = gMapControl1.FromLocalToLatLng(e.X, e.Y);
                    var marker = new GMapMarkerGoogleGreen(gP);                   
                    gMapControl1.CurrentPosition = gP;
            }catch(Exception ex)
                log.WriteLog("Form1.gMapControl1_MouseUp", "Err:"+ex.Message);

Map centerred to click place (gP), but marker didn't appear.

I tried doing this on empty project - it worked fine,
but when I tried to do this on my work project (Sharpmap + GMap.Net) I could not draw marker on the map (((

What problem could be in this case?


I've just tried to debug it and saw - gMapControl1.Overlays.Count=0 after 

_gMapLayerTop = new GMapOverlay(gMapControl1, "top");

Can you suggest a reason a top layer hasn't added to layers gMapControl?

well you have to add your layer to map, gMapControl1.Overlays.Add(gMapLayerTop);
