Hi conrad1209,

An approach you could use is the following:

XAML:
        <igMap:XamMap x:Name="xamMap">
            <igMap:XamMap.Layers>
                <igMap:MapLayer x:Name="statesLayer" Imported="statesLayer_Imported">
                    <igMap:MapLayer.Reader>
                        <igMap:ShapeFileReader Uri="Shapefiles/usa_st" DataMapping="Name,Caption=STATE_NAME"/>
                    </igMap:MapLayer.Reader>
                </igMap:MapLayer>

                <igMap:MapLayer x:Name="symbolLayer"/>
            </igMap:XamMap.Layers>
        </igMap:XamMap>

CB:
private List<MapElement> _highlightedElements = new List<MapElement>(3);

        public MainPage()
        {
            InitializeComponent();

            xamMap.ElementHoverAction = ElementHoverAction.None;
            xamMap.ElementHover += xamMap_ElementHover;
            xamMap.ElementUnhover += xamMap_ElementUnhover;
        }

        private void statesLayer_Imported(object sender, Infragistics.Controls.Maps.MapLayerImportEventArgs e)
        {
            if (e.Action == MapLayerImportAction.End)
            {
                Rect worldRect = xamMap.Layers[0].WorldRect;

                foreach (MapElement elementsymb in this.xamMap.Layers[0].Elements)
                {
                    SymbolElement myS = new SymbolElement();

                    Point symOrigin = new Point(elementsymb.WorldRect.X + .5 * elementsymb.WorldRect.Width, elementsymb.WorldRect.Y + 0.5 * elementsymb.WorldRect.Height);

                    myS.SymbolOrigin = symOrigin;
                    myS.SymbolType = MapSymbolType.Hourglass;
                    myS.SymbolSize = 15;
                    myS.Fill = new SolidColorBrush(System.Windows.Media.Colors.Orange);
                    myS.Value = elementsymb.Value;
                    myS.Name = "Symbol" + elementsymb.Name.ToString();

                    xamMap.Layers[1].Elements.Add(myS);

                    worldRect = xamMap.Layers[1].WorldRect;
                    worldRect.Union(myS.WorldRect);

                    xamMap.Layers[1].WorldRect = worldRect;

                    myS = null;
                }
            }
        }

        void xamMap_ElementUnhover(object sender, MapElementHoverEventArgs e)
        {
            foreach (var element in _highlightedElements)
            {
                element.Fill = new SolidColorBrush(System.Windows.Media.Colors.Orange);
            }

            _highlightedElements.Clear();
        }

        private void xamMap_ElementHover(object sender, MapElementHoverEventArgs e)
        {
            if (e.Element.Name == "SymbolKansas")
            {
                _highlightedElements.Add(e.Element);
                _highlightedElements.Add(xamMap.Layers[1].Elements["SymbolColorado"].Single());
                _highlightedElements.Add(xamMap.Layers[1].Elements["SymbolNebraska"].Single());

                foreach (var element in _highlightedElements)
                {
                    element.Fill = new SolidColorBrush(Colors.Red);
                }
            }
        }

Thank you, I might have miss phrased my question. I need to do that for Symbols not elements.
