Syntax

Visual Basic (Declaration)
C#

Public Function New( _
   ByVal fields As List(Of String), _
   Optional ByVal symbolTemplate As CIMSymbolReference, _
   Optional ByVal colorRamp As CIMColorRamp, _
   Optional ByVal defaultSymbol As CIMSymbolReference, _
   Optional ByVal useDefaultSymbol As Boolean _
)

public UniqueValueRendererDefinition( 
   List<string> fields,
   CIMSymbolReference symbolTemplate,
   CIMColorRamp colorRamp,
   CIMSymbolReference defaultSymbol,
   bool useDefaultSymbol
)

Parameters

fields: One or more fields be used to get unique values or combination of values from.
symbolTemplate: A symbol that will be used to draw features whose values are not found in values list.
colorRamp: A color ramp be used to pick color for symbols from.
defaultSymbol: A symbol that will be used to draw features whose values are not found in values list.
useDefaultSymbol: A boolean indicates whether the DefaultSymbol will be used to draw features whose values are not found in the values list or not.

Example

Set unique value renderer to the selected feature layer of the active map

{
    //field to be used to retrieve unique values
    //Note: Run within a QueuedTask
    var fields = new List<string> { "Type" };
    //constructing a point symbol as a template symbol
    CIMPointSymbol pointSym = SymbolFactory.Instance.ConstructPointSymbol(
        ColorFactory.Instance.GreenRGB, 16.0, SimpleMarkerStyle.Pushpin);
    CIMSymbolReference symbolPointTemplate = pointSym.MakeSymbolReference();

    //constructing renderer definition for unique value renderer
    UniqueValueRendererDefinition uniqueValueRendererDef =
  new UniqueValueRendererDefinition(fields, symbolPointTemplate);

    //creating a unique value renderer
    CIMUniqueValueRenderer uniqueValueRenderer = featureLayer.CreateRenderer(uniqueValueRendererDef) as CIMUniqueValueRenderer;

    //setting the renderer to the feature layer
    featureLayer.SetRenderer(uniqueValueRenderer);
}
