if you really have no idea:

var top = new GMapOverlay();
map.Overlays.Add(top);

var marker = new GMarkerGoogle(MainMap.Position, GMarkerGoogleType.arrow);
top.Markers.Add(marker);

Hi Radioman,
   i tried the above code but it gave me only one red cross on the window instead of the map..

    But i've tried something like this but its not working, can you please check the snippet and  tell me where i'm doing the mistake....

for (int i = 0; i <= dataGrid1.Rows.Count; i++) 
            {
                 foreach (DataGridViewRow row in dataGrid1.Rows)
                {              
                      var lat = double.Parse((dataGrid1.Columns[1].ToString()), CultureInfo.InvariantCulture);
                      var lng = double.Parse((dataGrid1.Columns[2].ToString()), CultureInfo.InvariantCulture);
                      MainMap.Position = new PointLatLng(lat, lng);
                      GMarkerGoogle m = new GMarkerGoogle(MainMap.Position, GMarkerGoogleType.green_pushpin);
                      objects.Markers.Add(m);
                }
           }
