Difficulty Adding Graphics

CraigPatterson

I'm attempting to create a simple Mark Up Add In.  I'm able to create the Draw object, set the correct draw mode, and enable it, but the graphic doesn't get added to the map. 

Here is my DrawComplete Method...

         private void MarkUpDrawObject_DrawComplete(object sender, ESRI.ArcGIS.Client.DrawEventArgs args)         {             // retrieve DrawingGraphics Layer object             GraphicsLayer graphicsLayer = MapApplication.Current.Map.Layers["MarkUpGraphicsLayer"] as GraphicsLayer;              if (graphicsLayer == null)             {                 graphicsLayer = new GraphicsLayer()                 {                     ID = "MarkUpGraphicsLayer",                                          Renderer = new SimpleRenderer()                     {                         Symbol =  new SimpleMarkerSymbol()                             {                                 Color = new SolidColorBrush(Color.FromArgb(0, 255,0,0)),                                 Size = 12                             }                     }                 };                  graphicsLayer.SetValue(MapApplication.LayerNameProperty, "Mark Up");                  MapApplication.Current.Map.Layers.Add(graphicsLayer);             }              //// create graphic object to hold new drawing             ESRI.ArcGIS.Client.Graphic graphic = new ESRI.ArcGIS.Client.Graphic()             {                 Geometry = args.Geometry,                 Symbol = _activeMarkUpSymbol,             };              ////add it to the map             graphicsLayer.Graphics.Add(graphic);              // Turn off drawing mode otherwise new graphics may be drawn during edit             // This returns the map to normal mode, pan on click             MarkUpDrawObject.IsEnabled = false;         }

Here is where I set my Symbol and enable my draw mode

        private void DrawPointButton_Click(object sender, RoutedEventArgs e)         {             MarkUpDrawObject.DrawMode = DrawMode.Point;             MarkUpDrawObject.IsEnabled = true;              _activeMarkUpSymbol = new SimpleMarkerSymbol()             {                 Color = new SolidColorBrush(Color.FromArgb(0, 255,0,0)),                 Size = 12             };         }

The graphic layer is added to the layer list, so I know that's not the issue.  I think it may have something to do with my symbol.

Any ideas on what may be wrong?

Thanks,

GG,

Thanks for all of the advice.  I got this working.  The problem was that Viewer was overwriting my graphics symbology.  I configured the layer and checked, "The symbols defined here are superseded by the symbols on the individual graphics, if any"
