Draw Graphics Tool

ScottBailey — Wed, 20 Jun 2012 19:25:02 GMT

I have converted the DrawGraphics tool http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#DrawGraphics to a Viewer addin. Everything works fine except for the editor check box. I have tried a ton of different things but the edit geometry box is not functional. It has something to do with the MouseLeftButtonUp event. I'm not sure whats going on. Code is below.

C#
namespace DrawGraphics.AddIns
{
    public partial class DrawGraphicsDialog : UserControl
    {
        private Draw MyDrawObject;
        private Symbol _activeSymbol = null;
        GraphicsLayer graphicsLayer;

        public Map MyMap
        {
            get { return MapApplication.Current.Map; }
        }


        public GraphicsLayer MyGraphicsLayer
        {
            get { return MyMap.Layers["MyGraphicsLayer"] as GraphicsLayer; }
        }

        public DrawGraphicsDialog()
        {
            InitializeComponent();

            graphicsLayer = MyGraphicsLayer;

            if (graphicsLayer == null)
            {
                graphicsLayer = createGraphicsLayer();
                MapApplication.Current.Map.Layers.Add(graphicsLayer);
            }

            MyDrawObject = new Draw(MyMap)
            {
                LineSymbol = LayoutRoot.Resources["DrawLineSymbol"] as LineSymbol,
                FillSymbol = LayoutRoot.Resources["DrawFillSymbol"] as FillSymbol
            };
            MyDrawObject.DrawComplete += MyDrawObject_DrawComplete;
        }

        private void MyDrawObject_DrawComplete(object sender, ESRI.ArcGIS.Client.DrawEventArgs args)
        {


            ESRI.ArcGIS.Client.Graphic graphic = new ESRI.ArcGIS.Client.Graphic()
            {
                Geometry = args.Geometry,
                Symbol = _activeSymbol,
            };
            graphicsLayer.Graphics.Add(graphic);
            UnSelectTools();
            MyDrawObject.IsEnabled = false;
        }

        private void GraphicsLayer_MouseLeftButtonUp(object sender, GraphicMouseButtonEventArgs e)
        {
            if (EnableEditVerticesScaleRotate.IsChecked.Value)
            {
                MyDrawObject.DrawMode = DrawMode.None;
                UnSelectTools();
                Editor editor = LayoutRoot.Resources["MyEditor"] as Editor;
                if (e.Graphic != null && !(e.Graphic.Geometry is ESRI.ArcGIS.Client.Geometry.MapPoint))
                {
                    editor.EditVertices.Execute(e.Graphic);
                }
            }
        }

        private void UnSelectTools()
        {
            foreach (UIElement element in MyStackPanel.Children)
                if (element is Button)
                    VisualStateManager.GoToState((element as Button), "UnSelected", false);
        }

        private void Tool_Click(object sender, RoutedEventArgs e)
        {
            UnSelectTools();

            VisualStateManager.GoToState(sender as Button, "Selected", false);

            switch ((sender as Button).Tag as string)
            {
                case "DrawPoint":
                    MyDrawObject.DrawMode = DrawMode.Point;
                    _activeSymbol = LayoutRoot.Resources["DefaultMarkerSymbol"] as Symbol;
                    break;
                case "DrawPolyline":
                    MyDrawObject.DrawMode = DrawMode.Polyline;
                    _activeSymbol = LayoutRoot.Resources["DefaultLineSymbol"] as Symbol;
                    break;
                case "DrawPolygon":
                    MyDrawObject.DrawMode = DrawMode.Polygon;
                    _activeSymbol = LayoutRoot.Resources["DefaultFillSymbol"] as Symbol;
                    break;

                default:
                    MyDrawObject.DrawMode = DrawMode.None;
                    graphicsLayer.ClearGraphics();
                    break;
            }

            MyDrawObject.IsEnabled = (MyDrawObject.DrawMode != DrawMode.None);
        }

       private GraphicsLayer createGraphicsLayer()
        {
            GraphicsLayer gl = new GraphicsLayer()
            {
                ID = "MyGraphicsLayer",


            };

            // Set layer name in Map Contents
            gl.SetValue(MapApplication.LayerNameProperty, "MyGraphicsLayer");
            return gl;
        }


    }
}

Hi Scott,
Did you ever have any luck getting this working? It looks like a great tool.

Has anybody got a draw tool working with the Silverlight viewer?

That would be super awesome.
