Asma,

Yes, this gives the basic recipe. And I've been able to host the control in a ElementHost control. However so far I can't get the shapefile to be displayed. and I was hoping also on some guidance on the best way of loading some 5000 points of intetest and making them clickable.

Finaly got the shapefile to display, but still no luck placing points of interest on the map. 

The elements seem to be there but not displayed

my xaml file is ...

                </ig:XamMap.Layers>
            </ig:XamMap>
        </DockPanel>
    </Grid>
</UserControl>

with cs file of control 

namespace WPFControl
{
    /// <summary>
    /// Interaction logic for UserControl1.xaml
    /// </summary>
    public partial class Map : UserControl
    {
        public MapLayerCollection Layers
        {
            get { return xamMap1.Layers; }
            set { xamMap1.Layers = value; }
 
 
        }
 
        public Rect WorldRect
        {
            get { return xamMap1.WorldRect; }
            set { xamMap1.WorldRect = value; }
        }
 
        public Projection MapProjection
        {
            get { return xamMap1.MapProjection; }
            set { xamMap1.MapProjection = value; }
        }
 
        public event MapElementClickEventHandler ElementClick
        {
            add { xamMap1.ElementClick += value; }
            remove { xamMap1.ElementClick -= value; }
        }
 
        public Map()
        {
            InitializeComponent();
            
        }
    }
}

and Mainform code which has the ElementHost control

 public MainForm()
        {
            service = new SPOTA1WebServiceClient();
 
            InitializeComponent();
 
            ultraChart1.Visible = false;
 
            mapControl.ElementClick += new MapElementClickEventHandler(mapControl_ElementClick);
 
            StationPosition[] stations = service.GetStationPosition();
 
            foreach (StationPosition stationPosition in stations)
            {
                System.Windows.Point origin = mapControl.MapProjection.ProjectToMap(new System.Windows.Point(stationPosition.Longitude, stationPosition.Latitude));
                SymbolElement element = new SymbolElement() { SymbolOrigin = origin, Caption = stationPosition.Name, Value=stationPosition.Code, SymbolType = MapSymbolType.Diamond, SymbolSize = 5,  };
 
                mapControl.Layers["Stations"].Elements.Add(element);
 
                stationPositionBindingSource.Add(stationPosition);
            }
           
            
        }
 
        void mapControl_ElementClick(object sender, MapElementClickEventArgs e)
        {
            if (e.Element.GetType().Equals(typeof(SymbolElement)))
                updateGrid2(Convert.ToInt32(e.Element.Value));
        }

Thanks that worked
