Saving data lat/lng into db from google maps api?

Question

I am using asp.net c# and google maps api. I want user can set route or markers on the map and I can save the points in the sql for showing them again.

There is some code @Chad Killingsworth wrote it for routing but how can I catch the lat/lng and write to db? polyline snap to road using google maps api v3 http://people.missouristate.edu/chadkillingsworth/mapsexamples/snaptoroad.htm

Or this is what I want but in php, how can I do that with asp.net? How can I know the points and record db?

Answer 1

you can fetch the value like this, then save the value.

google.maps.event.addListener(map, "click", function(event){

                var p = new google.maps.LatLng(event.latLng.lat(), event.latLng.lng());
                marker.setPosition(p);
                p.lng();
                p.lat();   

                });
