Class SimpleLabelExpression
An expression script using the Simple REST language.
Namespace: Esri.ArcGISRuntime.Mapping.Labeling
Assembly: Esri.ArcGISRuntime.dll
Syntax
public class SimpleLabelExpression : LabelExpression
Remarks
The label Simple expression expects to hold a legal, Simple script and to be read and evaluated by a Simple expression
interpreter. An example expression that combines text with a field value is: "State: " CONCAT [State_Name]
.
Note that quotes are needed around the literal text. See https://developers.arcgis.com/documentation/common-data-types/labeling-objects.htm for full documentation on the labelExpression syntax and functions.
Warning: If the expression attempts to use attributes which don't exist then no label will be produced.
This is distinct from the attribute existing but having a null
or empty value,
which can form part of the produced text label.
