In This Topic
    SubtypeGroupLayerCreationParams Constructor(Uri)
    In This Topic
    Creates a parameter object with System.Uri.
    Syntax
    public SubtypeGroupLayerCreationParams( 
       Uri uri
    )
    Public Function New( _
       ByVal uri As Uri _
    )

    Parameters

    uri
    A System.Uri represents the path or url to a dataset or .lyrx or .lpkx file.
    Example
    Create a new SubTypeGroupLayer
    var subtypeGroupLayerCreateParam = new SubtypeGroupLayerCreationParams
    (
        new Uri(@"c:\data\SubtypeAndDomain.gdb\Fittings")
    );
    
    // Define Subtype layers
    //At 2.x - var rendererDefn1 = new UniqueValueRendererDefinition(new string[] { "type" });
    var rendererDefn1 = new UniqueValueRendererDefinition(new List<string> { "type" });
    var renderDefn2 = new SimpleRendererDefinition()
    {
      SymbolTemplate = SymbolFactory.Instance.ConstructPointSymbol(
              CIMColor.CreateRGBColor(255, 0, 0), 8, SimpleMarkerStyle.Hexagon).MakeSymbolReference()
    };
    subtypeGroupLayerCreateParam.SubtypeLayers = new List<SubtypeFeatureLayerCreationParams>()
    {
      //define first subtype layer with unique value renderer
      //At 2.x - new SubtypeFeatureLayerCreationParams(new UniqueValueRendererDefinition(new string[] { "type" }), 1),
      new SubtypeFeatureLayerCreationParams(new UniqueValueRendererDefinition(new List<string> { "type" }), 1),
    
      //define second subtype layer with simple symbol renderer
      new SubtypeFeatureLayerCreationParams(renderDefn2, 2)
    };
    
    // Define additional parameters
    //At - 2.x subtypeGroupLayerCreateParam.DefinitionFilter = new CIMDefinitionFilter()
    //{
    //  Name = "IsActive",
    //  DefinitionExpression = "Enabled = 1"
    //};
    subtypeGroupLayerCreateParam.DefinitionQuery = new DefinitionQuery(whereClause: "Enabled = 1", name: "IsActive");
    subtypeGroupLayerCreateParam.IsVisible = true;
    subtypeGroupLayerCreateParam.MinimumScale = 50000;
    
    SubtypeGroupLayer subtypeGroupLayer2 = LayerFactory.Instance.CreateLayer<SubtypeGroupLayer>(
                  subtypeGroupLayerCreateParam, MapView.Active.Map);
