Hi

I Use esri sample code of Spatial_Query http://resources.arcgis.com/en/help/silverlight-api/samples/start.htm#SpatialQuery in my viewer.

But when I Use point feature in a service it dosnot select points.

I think the problem comes from QueryTask_ExecuteCompleted event handeler.

 private void QueryTask_ExecuteCompleted(object sender, ESRI.ArcGIS.Client.Tasks.QueryEventArgs args)
        {
            FeatureSet featureSet = args.FeatureSet;

            if (featureSet == null || featureSet.Features.Count < 1)
            {
                MessageBox.Show("No features returned from query");
                return;
            }

            if (featureSet != null && featureSet.Features.Count > 0)
            {
                foreach (Graphic feature in featureSet.Features)
                {
                    feature.Symbol = LayoutRoot.Resources["ResultsFillSymbol"] as FillSymbol;
                    selectionGraphicslayer.Graphics.Insert(0, feature);
                }
                ResultsDisplay.Visibility = Visibility.Visible;
            }
            MyDrawObject.IsEnabled = true;
        }

I think FillSymbol dosnot work for point feature. I changed it with MarkerSymbol but it didnot work;

I cant solve the problem. please help me .

FillSymbols are for Polygons, LineSymbols for Polylines and MarkerSymbols for MapPoint. No exceptions.
