Hello,
I would like to show multiple markers, but of different colors. I seem to be having difficulty doing so with the following code. I have read that it is not recommended to use multiple marker layers. Please advise as to how I may accomplish this. Code follows:
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
Map1.MapBackground.BackgroundBrush = new GeoSolidBrush(GeoColor.FromHtml("#B3C6D4"));
Map1.CurrentExtent = new RectangleShape(-88.1422, 42.4009, -87.5169, 41.4529);
Map1.MapUnit = GeographyUnit.DecimalDegree;
//Map1.MapTools.PanZoom.Enabled = true;
Map1.MapTools.PanZoomBar.Enabled = true;
ShapeFileFeatureLayer defaultLayer = new ShapeFileFeatureLayer(Server.MapPath("~/Map/ILlkA.shp"));
defaultLayer.ZoomLevelSet.ZoomLevel01.CustomStyles.Add(LineStyles.LocalRoad1);
defaultLayer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;
defaultLayer.Name = ("defaultLayer");
ShapeFileFeatureLayer railLayer = new ShapeFileFeatureLayer(Server.MapPath("~/Map/ILlkB.shp"));
railLayer.ZoomLevelSet.ZoomLevel01.CustomStyles.Add(LineStyles.Railway1);
railLayer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;
ShapeFileFeatureLayer defaultStreetsLabelLayer = new ShapeFileFeatureLayer(Server.MapPath("~/Map/ILlkA.shp"));
defaultStreetsLabelLayer.ZoomLevelSet.ZoomLevel01.DefaultTextStyle = TextStyles.LocalRoad1("FENAME");
defaultStreetsLabelLayer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;
defaultStreetsLabelLayer.DrawingMarginPercentage = 100;
defaultStreetsLabelLayer.Name = ("defaultStreetsLabelLayer");
Map1.StaticOverlay.Layers.Add(railLayer);
Map1.StaticOverlay.Layers.Add(defaultLayer);
Map1.StaticOverlay.TileType = TileType.MultipleTile;
Map1.DynamicOverlay.Layers.Add(defaultStreetsLabelLayer);
// The following two lines of code enable the client and server caching.
// If you enable these features it will greatly increase the scalability of your
// mapping application however there some side effects that may be counter intuitive.
// Please read the white paper on web caching or the documentation regarding these methods.
Map1.StaticOverlay.ClientCache.CacheId = "defaultOverlay";
Map1.StaticOverlay.ServerCache.CacheDirectory = MapPath("~/ImageCache/" + Request.Path);
InMemoryFeatureLayer shapeLayer = new InMemoryFeatureLayer();
shapeLayer.ZoomLevelSet.ZoomLevel01.DefaultPointStyle =
PointStyles.CreateSimplePointStyle(PointSymbolType.Circle, GeoColor.StandardColors.Blue, 5);
shapeLayer.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;
Map1.DynamicOverlay.Layers.Add("pointShapeLayer", shapeLayer);
CreatePoints(shapeLayer, "-87.8225020", "42.3754010");
CreatePoints(shapeLayer, "-88.08842", "42.19746");
CreatePoints(shapeLayer, "-88.063", "42.21907");
CreateARedMarker("1", -87.8225020, 42.3754010);
CreateAGreenMarker("2", -88.08842, 42.19746);
CreateAGreenMarker("3", -88.063, 42.21907);
shapeLayer.Open();
Map1.CurrentExtent = shapeLayer.GetBoundingBox();
shapeLayer.Close();
}
}
private void CreatePoints(InMemoryFeatureLayer layer, string lon, string lat)
{
Feature pointFeature = new Feature(new PointShape(
double.Parse(lon, CultureInfo.InvariantCulture), double.Parse(lat, CultureInfo.InvariantCulture)));
layer.InternalFeatures.Add(pointFeature.Id, pointFeature);
}
private void CreateAGreenMarker(string key, double lon, double lat)
{
StringBuilder contentHtml = new StringBuilder();
contentHtml.Append("")
.Append("This is a green sample hover popup")
.Append("");

Map1.MarkerOverlay.ZoomLevelSet.ZoomLevel01.DefaultMarkerStyle.Popup.IsVisible = false;
Map1.MarkerOverlay.ZoomLevelSet.ZoomLevel01.DefaultMarkerStyle.Popup.AutoPan = true;
Map1.MarkerOverlay.ZoomLevelSet.ZoomLevel01.ApplyUntilZoomLevel = ApplyUntilZoomLevel.Level20;
}
private void CreateARedMarker(string key, double lon, double lat)
{

.Append("This is a red sample hover popup")
.Append("");
Map1.MarkerOverlay.Features.Add(key, new Feature(lon, lat));
