Getting Driving Directions using lat/long instead of physical addresses

Question

Hi all,
If I am to pass lat/long instead of physcial addresses for both starting and ending point of a route, how would I pass that?

The live sample shows how to get directions using physical addresses.

Could anyone provide a brief example?

Thanks

It's the other way : X means longitude and Y means latitude.

thank you!

for class MapPoint, X property means latitude, and Y property means longitude? or is it the other way around?

Ah okay I see what you're doing now.

In this case, you do not need LocationToAddressAsync nor AddressToLocationAsync.

Using this sample http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#RoutingDirections, I commented out code for initializing locator and subscribing to its events. Instead, I subscribed to MouseClick.
 if (_stops.Count < 2)
  _stops.Add(new Graphic(){Geometry = e.MapPoint});
 if(_stops.Count == 2)
  _routeTask.SolveAsync(_routeParams);

Since you already have the lat/lon values, you do not need to get MapPoints from an event such as MouseClick, you can simply do:_stops.Add(new Graphic(){Geometry = new MapPoint(lat, lon}); // for both start and end location.

That should be all you need to do.

Hi Jennifer,
thanks for the response. That did clear out the confusion. I found the bug that was causing the function to not work properly.

Let me confirm this with you -- for class MapPoint, X property means latitude, and Y property means longitude? or is it the other way around?
