                circle.Clickable = true;
                circle.FillColor =  _tipo=="MAGISTER"?  Color.Red: Color.DarkGray;
                circle.FillOpacity = .5F;
                circle.StrokeColor = Color.MidnightBlue;
                circle.StrokeWeight = 5;
                circle.Radius = 200000;
                circle.TargetControlID = "GoogleMap1";
                circle.Center = new LatLng(Convert.ToDouble(lat.Replace('.',',')), Convert.ToDouble(lng.Replace('.',',')));
                GoogleMap1.Overlays.Add(circle);

                //i++;
            }
            catch (Exception)
            {
                
                continue;
            }
           
        }

the last circle drawn on the map, triggers the OnClientClick event, the rest is not triggered.

any ideas?

thanks guys
