featureLayer.UpdateCompleted problem?

[المشرف العام]

I am trying to show a particular kind of rendering to my geometry when a user clicks on the record of a feature data grid and zooms to the selection but cant figure out as to what i am doing wrong.. ..

here is my code for the featureLayerFromMap.UpdateCompleted += new System.EventHandler(fslayer_UpdateCompleted);

void fslayer_UpdateCompleted(object sender, System.EventArgs e) { ESRI.ArcGIS.Client.FeatureLayer featureLayerFromMap = (ESRI.ArcGIS.Client.FeatureLayer)(_mapService.Map.Layers["FeatureLayerControlLayer"]); //*** Flashing of Polyline and Polygon when zoomed from a feature data grid record _objectIdDic = new Dictionary(); int count = 0; featureLayerFromMap.Graphics.ToList().ForEach(x => _objectIdDic.Add(x.Attributes["OBJECTID"].ToString(), count++.ToString())); if (featureLayerFromMap.Graphics.Count > 0) { if (featureLayerFromMap.Graphics[0].Geometry.GetType() == typeof(ESRI.ArcGIS.Client.Geometry.Polygon)) featureLayerFromMap.Renderer = this._mapLayout.Resources["PolygonGraphicLyrSelectedRenderer"] as IRenderer; else if (featureLayerFromMap.Graphics[0].Geometry.GetType() == typeof(ESRI.ArcGIS.Client.Geometry.Polyline)) featureLayerFromMap.Renderer = this._mapLayout.Resources["PolylineGraphicLyrSelectedRenderer"] as IRenderer; } }The feature layer is provided from a selection in a combo box..Can someone guide me on this?
