OnPolygonClick not firing, IsHitTestVisible

Just downloaded the latest version (and tried with some of the other older versions). OnPolygonClick, OnPolygonEnter and OnPolygonLeave are not firing in the WinForms version.

On my form load event I put the following in...

            myMap.OnPolygonClick += new PolygonClick(myMap_OnPolygonClick);

            myMap.OnPolygonEnter += new PolygonEnter(myMap_OnPolygonEnter);

            myMap.OnPolygonLeave += new PolygonLeave(myMap_OnPolygonLeave);

I create a polygon with the following..

            List<PointLatLng> polygonPoints = new List<PointLatLng>();            foreach (GMapMarker m in top.Markers)            {                if (m is GMapMarker)                {                    m.Tag = polygonPoints.Count;                    polygonPoints.Add(m.Position);                }            }            GMapPolygon polygon = new GMapPolygon(polygonPoints, "polygon tester");            top.Polygons.Add(polygon);

Which draws the polygon on the map.

I create a myMap_OnPolygonClick event and put a breakpoint in but it never gets hit - same with the enter and leave events (Marker works correctly)


Have I missed something or done something wrong RadioMan?

Thanks Charlotte

Figured it out - needed to add IsHitTestVisible when creating my polygons :)

yes, by default polygons do not receive events
