    RendererDefinition Property (FeatureLayerCreationParams)
    In This Topic
    Gets and sets a RendererDefinition.
    Syntax
    public RendererDefinition RendererDefinition {get; set;}
    Public Property RendererDefinition As RendererDefinition
    Example
    Create layer with create-params
    var flyrCreatnParam = new FeatureLayerCreationParams(new Uri(@"c:\data\world.gdb\cities"))
    {
      Name = "World Cities",
      IsVisible = false,
      MinimumScale = 1000000,
      MaximumScale = 5000,
      // At 2.x - DefinitionFilter = new CIMDefinitionFilter()
      //{
      //  DefinitionExpression = "Population > 100000",
      //  Name = "More than 100k"
      //},
      DefinitionQuery = new DefinitionQuery(whereClause: "Population > 100000", name: "More than 100k"),
      RendererDefinition = new SimpleRendererDefinition()
      {
        SymbolTemplate = SymbolFactory.Instance.ConstructPointSymbol(
          CIMColor.CreateRGBColor(255, 0, 0), 8, SimpleMarkerStyle.Hexagon).MakeSymbolReference()
      }
    };
    
    var featureLayer = LayerFactory.Instance.CreateLayer<FeatureLayer>(
      flyrCreatnParam, map);
    Apply Symbology from a Layer in the TOC
    //Note: Call within QueuedTask.Run()
    if (MapView.Active.Map == null) return;
    
    //Get an existing Layer. This layer has a symbol you want to use in a new layer.
    var lyr = MapView.Active.Map.GetLayersAsFlattenedList().OfType<FeatureLayer>()
          .Where(l => l.ShapeType == esriGeometryType.esriGeometryPoint).FirstOrDefault();
    //This is the renderer to use in the new Layer
    var renderer = lyr.GetRenderer() as CIMSimpleRenderer;
    //Set the Dataconnection for the new layer
    Geodatabase geodatabase = new Geodatabase(
      new FileGeodatabaseConnectionPath(new Uri(@"E:\Data\Admin\AdminData.gdb")));
    FeatureClass featureClass = geodatabase.OpenDataset<FeatureClass>("Cities");
    var dataConnection = featureClass.GetDataConnection();
    //Create the definition for the new feature layer
    var featureLayerParams = new FeatureLayerCreationParams(dataConnection)
    {
      RendererDefinition = new SimpleRendererDefinition(renderer.Symbol),
      IsVisible = true,
    };
    //create the new layer
    LayerFactory.Instance.CreateLayer<FeatureLayer>(
      featureLayerParams, MapView.Active.Map);
    Create a stream layer with a simple renderer
    var url = @"https://geoeventsample1.esri.com:6443/arcgis/rest/services/LABus/StreamServer";
    var uri = new Uri(url, UriKind.Absolute);
    //Must be on QueuedTask!
    var createParams = new FeatureLayerCreationParams(uri)
    {
      RendererDefinition = new SimpleRendererDefinition()
      {
        SymbolTemplate = SymbolFactory.Instance.ConstructPointSymbol(
                            ColorFactory.Instance.BlueRGB,
                            12,
                     SimpleMarkerStyle.Pushpin).MakeSymbolReference()
      }
    };
    var streamLayer = LayerFactory.Instance.CreateLayer<StreamLayer>(
                        createParams, map);
