Gets or sets value which indicates whether the DataTemplate will be re-applied to the map items when zoom level is changed. It makes possible creation of the DataTemplateSelector which will return data templates depends on the map zoom level.
public bool AllowDataTemplateForZoomLevel { get; set; }Pay attention that re-applying of the data templates is resource consuming operation. Use this feature when you really need it only.
Gets or sets clustered data source.
public ClusteredDataSource ClusteredDataSource { get; set; }Gets or sets map shapes colorizer.
public IMapShapeColorizer Colorizer { get; set; }Gets the value mappings that constitute the data mappings for a layer.
public DataMappingCollection DataMappings { get; }DefaultInformationLayerTemplate
DataTemplate
Gets or sets the default data template.
public DataTemplate DefaultInformationLayerTemplate { get; set; }Gets or sets default highlight shape fill properties. If highlight fill properties aren't set for MapShape object then this properties will be used.
public MapShapeFill HighlightFill { get; set; }MapShapeDataTemplate
DataTemplate
Gets or sets the data template for map shapes.
public DataTemplate MapShapeDataTemplate { get; set; }Gets or sets map shape reader. The map shapes are loaded by this reader will be added to the information layer automatically.
public MapShapeReaderBase Reader { get; set; }Gets or sets geographical region is covered by this layer.
public LocationRect Region { get; set; }Gets or sets geographical region size mode.
public RegionSizeMode RegionMode { get; set; }Gets or sets default shape fill properties. If fill properties aren't set for MapShape object then this properties will be used.
