How to get the coordinates of a symbol (point)?

Hi,

How to get the coordinates of a symbol (point)?

My problem that 's I can not get the center of the Graphic.

Here is my function:

private bool isHandler;  private void FeatureLayer_MouseLeftButtonDown(object sender, GraphicMouseButtonEventArgs args)         {             if (args.Graphic != null)             {                  this.isHandler = true;                  Point screenPoint = args.GetPosition(Map);                 MapPoint mapPoint = Map.ScreenToMap(screenPoint);                 if (Map.WrapAroundIsActive)                 {                     mapPoint = ESRI.ArcGIS.Client.Geometry.Geometry.NormalizeCentralMeridian(mapPoint) as MapPoint;                     CoordPointX.Text = Math.Round(mapPoint.X, 4).ToString();                     CoordPointY.Text = Math.Round(mapPoint.Y, 4).ToString();                 }                  args.Graphic.MouseMove += (s, e) =>                         {                             if (this.isHandler == true)                             {                                 Point screenPointMove = e.GetPosition(Map);                                 MapPoint mapPointMove = Map.ScreenToMap(screenPointMove);                                 if (Map.WrapAroundIsActive)                                 {                                     mapPointMove = ESRI.ArcGIS.Client.Geometry.Geometry.NormalizeCentralMeridian(mapPointMove) as MapPoint;                                     CoordPointX.Text = Math.Round(mapPointMove.X, 4).ToString();                                     CoordPointY.Text = Math.Round(mapPointMove.Y, 4).ToString();                                 }                              }                         };                  args.Graphic.MouseLeftButtonUp += (u, k) =>                 {                      Point screenPointUp = k.GetPosition(Map);                     this.isHandler = false;                      MapPoint mapPointUp = Map.ScreenToMap(screenPointUp);                     if (Map.WrapAroundIsActive)                     {                         mapPointUp = ESRI.ArcGIS.Client.Geometry.Geometry.NormalizeCentralMeridian(mapPointUp) as MapPoint;                         CoordPointX.Text = Math.Round(mapPointUp.X, 4).ToString();                         CoordPointY.Text = Math.Round(mapPointUp.Y, 4).ToString();                     }                  };              }         }

This is an solution :

        private bool isHandler;

        private void FeatureLayer_MouseLeftButtonDown(object sender, GraphicMouseButtonEventArgs args)
        {
            if (args.Graphic != null)
            {

                this.isHandler = true;

                MapPoint point = args.Graphic.Geometry as MapPoint;

                Point screenPoint = Map.MapToScreen(point);
                CoordsSceenPoint.Text = string.Format("Screen Coords: X = {0}, Y = {1}", Convert.ToInt32(screenPoint.X), Convert.ToInt32(screenPoint.Y));

                MapPoint mapPoint = Map.ScreenToMap(screenPoint);
                if (Map.WrapAroundIsActive)
                {
                    mapPoint = ESRI.ArcGIS.Client.Geometry.Geometry.NormalizeCentralMeridian(mapPoint) as MapPoint;
                    CoordPointX.Text = Math.Round(mapPoint.X, 4).ToString();

                }

                                MapPoint pointMove = args.Graphic.Geometry as MapPoint;

                                Point screenPointMove = Map.MapToScreen(pointMove);
                                CoordsSceenPoint.Text = string.Format("Screen Coords: X = {0}, Y = {1}", Convert.ToInt32(screenPointMove.X), Convert.ToInt32(screenPointMove.Y));

                                MapPoint mapPointMove = Map.ScreenToMap(screenPointMove);
                                if (Map.WrapAroundIsActive)
                                {
                                    mapPointMove = ESRI.ArcGIS.Client.Geometry.Geometry.NormalizeCentralMeridian(mapPointMove) as MapPoint;
                                    CoordPointX.Text = Math.Round(mapPointMove.X, 4).ToString();
                                    CoordPointY.Text = Math.Round(mapPointMove.Y, 4).ToString();
                                }

                            }
                        };

                args.Graphic.MouseLeftButtonUp += (u, k) =>
                {
                    MapPoint pointUp = args.Graphic.Geometry as MapPoint;
                    Point screenPointUp = Map.MapToScreen(pointUp);
                    CoordsSceenPoint.Text = string.Format("Screen Coords: X = {0}, Y = {1}", Convert.ToInt32(screenPointUp.X), Convert.ToInt32(screenPointUp.Y));
                    this.isHandler = false;

                    MapPoint mapPointUp = Map.ScreenToMap(screenPointUp);
                    if (Map.WrapAroundIsActive)
                    {
                        mapPointUp = ESRI.ArcGIS.Client.Geometry.Geometry.NormalizeCentralMeridian(mapPointUp) as MapPoint;
                        CoordPointX.Text = Math.Round(mapPointUp.X, 4).ToString();
                        CoordPointY.Text = Math.Round(mapPointUp.Y, 4).ToString();
                    }

                };


            }
        }
