Question

I want to implement a Google Map on my .NET page. I used the tool from Subgurim,

I could add the components well, but when browsing the page, I get tons of Javascript errors like:

GUnload is undefined

And the map is not shown. I read many posts describing my problem, but the only hint seems to be the maps API was not loaded.

I got a API key from Google. I am not very familiar with the interface; I activated both Google maps API services (v2 and v3) and got a key from “API access” for both separately.

I downloaded the Subgurim Maps version 3.4.1.

string streetAddress = "100 Russell St. Melbourne. VIC. 3000. Australia";
string mapKey = ConfigurationManager.AppSettings["googlemaps.subgurim.net"];
Subgurim.Controles.GeoCode geoCode = GMap1.getGeoCodeRequest(streetAddress, mapKey);
Subgurim.Controles.GLatLng gLatLng = new Subgurim.Controles.GLatLng(geoCode.Placemark.coordinates.lat, geoCode.Placemark.coordinates.lng);

GMap1.setCenter(gLatLng, 16, Subgurim.Controles.GMapType.GTypes.Normal);
Subgurim.Controles.GMarker oMarker = new Subgurim.Controles.GMarker(gLatLng);
GMap1.addGMarker(oMarker);

Answer 1

The problem was that the GMap control I used was in part of the page that was set visible=”false”. This caused the Javascript error.
