    here is some code to add a path to a map using C#:

     

            <ig:XamMap Name="xamMap1">

                <ig:XamMap.Layers>

                    <ig:MapLayer Name="world">

                        <ig:MapLayer.Reader>

                            <ig:ShapeFileReader Uri="world" />

                        </ig:MapLayer.Reader>

                    </ig:MapLayer>

                    <ig:MapLayer Name="paths" />

                </ig:XamMap.Layers>

                <Button Height="25" Width="50" Content="click me" Click="Button_Click" />

            </ig:XamMap>

            private void Button_Click(object sender, RoutedEventArgs e)

            {

                Point denver = new Point(-105, 39);

                denver = this.xamMap1.MapProjection.ProjectToMap(denver);

                Point dallas = new Point(-96, 32);

                dallas = this.xamMap1.MapProjection.ProjectToMap(dallas);

     

                Point worldRectTopLeft = new Point(Math.Min(denver.X, dallas.X), Math.Min(denver.Y, dallas.Y));

                Point worldRectBottomRight = new Point(Math.Max(denver.X, dallas.X), Math.Max(denver.Y, dallas.Y));

                Rect worldRect = new Rect(worldRectTopLeft, worldRectBottomRight);

     

                PathElement el = new PathElement();

                MapPolyline oly = new MapPolyline();

                oly.Add(denver);

                oly.Add(dallas);

                el.Polylines = new MapPolylineCollection();

                el.Polylines.Add(oly);

                el.StrokeThickness = 5.0;

                el.Fill = new SolidColorBrush(Colors.Red);

     

                this.xamMap1.Layers["paths"].Elements.Add(el);

                this.xamMap1.Layers["paths"].WorldRect = worldRect;

            }
