I am trying to display places within 1 km from my current location on window phone 8 map control with google places API. I am using JSON parsing to fetch latitude, longitude and Name. Now i want name to be display like a tooltip when user tap on any place circle.

//Use google API to show POI
HttpClient client = new HttpClient();
string baseUrl = "https://maps.googleapis.com/maps/api/place/nearbysearch/json?location=" + position.Coordinate.Latitude + "," + position.Coordinate.Longitude + "&radius=1000&keyword=hospital&key=AIzaSyBCccOYAea2ITvgqNpIHcutuExQwzQctCk";
string googleResult = await client.GetStringAsync(baseUrl);

//Parse JSON data
JObject obj = JObject.Parse(googleResult);
JArray jarr = (JArray)obj["results"];

foreach(var item in jarr)
            {
                string name = (string)item.SelectToken("name");
                double lt = (double)item.SelectToken("geometry.location.lat");
                double lg = (double)item.SelectToken("geometry.location.lng");
                
                //Create a small circle to mark the current location.
                Ellipse myCircle2 = new Ellipse();
                myCircle2.Fill = new SolidColorBrush(Colors.Red);
                myCircle2.Height = 10;
                myCircle2.Width = 10;
                myCircle2.Opacity = 50;

                // Create a MapOverlay to contain the circle.
                MapOverlay myLocationOverlay2 = new MapOverlay();
                myLocationOverlay2.Content = myCircle2;
                myLocationOverlay2.PositionOrigin = new Point(0.5, 0.5);
                GeoCoordinate myGeoCoordinate2 = new GeoCoordinate(lt, lg);
                myLocationOverlay2.GeoCoordinate = myGeoCoordinate2;

                // Create a MapLayer to contain the MapOverlay.
                MapLayer myLocationLayer2 = new MapLayer();
                myLocationLayer2.Add(myLocationOverlay2);

                // Add the MapLayer to the Map.
                Bmap.Layers.Add(myLocationLayer2);

            }
