Dear all,

I am trying to populate Google Maps V3 with Multiple Markers from SQL Server 2012 Database table.

i am saving the latitude longitude in one column called GPS in this format 11.5642078,104.905664

my problem is the markers is show only one record do not appear all Marker in the maps. Mean that if in table have 20 record it will show 20 marker in maps, But now it can show only one marker in maps.

Please help me.
