Yep, I am not the first who is asking, but I didn't found an answer (maybe, because my english is bad). How to draw a polyline on a map? Not a route (direction), but just a polyline, like in JS Google Maps API with function Polyline. I can not understand.
Have a good read of this tutorial:
This should get you started:
GMapOverlay polyOverlay = new GMapOverlay("polygons"); IList<PointLatLng> points = new List<PointLatLng>(); points.Add(new PointLatLng(-25.969562,32.585789)); points.Add(new PointLatLng(-25.966205,32.588171)); GMapPolygon polygon = new GMapPolygon(points, "mypolygon"); polygon.Fill = new SolidBrush(Color.FromArgb(50, Color.Red)); polygon.Stroke = new Pen(Color.Red, 1); polyOverlay.Polygons.Add(polygon); gmap.Overlays.Add(polyOverlay);
