Class DictionarySymbolStyle
A dictionary symbol style object containing symbol primitives and rules for generating symbols from attribute values.
Namespace: Esri.ArcGISRuntime.Symbology
Assembly: Esri.ArcGISRuntime.dll
Syntax
public class DictionarySymbolStyle : SymbolStyleRemarks
A DictionarySymbolStyle is created either from a style file on disk (an SQLite database with a .stylx extension, created with ArcGIS Pro) or from a dictionary style file hosted on ArcGIS Online or an ArcGIS Enterprise portal (also referred to as a dictionary web style).
A DictionarySymbolStyle must contain a set of symbol primitives and a rule engine that parses input fields. The DictionarySymbolStyle assembles new symbols based on the input attribute values. DictionarySymbolStyle is often used to render symbols from a military specification (such as MIL-STD 2525D or APP-6B) but can also be used with a custom style.
A DictionarySymbolStyle is used in conjunction with a DictionaryRenderer to symbolize geoelements in a FeatureLayer or GraphicsOverlay.
Esri builds and maintains some dictionary web styles according to the US and NATO military symbol specifications. These desktop and web styles are hosted online and are publicly available. Refer to the ArcGIS Online Dictionary Symbology Styles group for the latest versions of the styles available.
