entityIdFieldName property

The name of the field from the DynamicEntityDataSourceInfo.fields collection containing values that uniquely identify each entity. For example, the track id field with a unique identifier for each track from track-aware data, or the object id field for discrete data.

The field name should reference a field in the DynamicEntityDataSourceInfo.fields collection. The values in this field help the underlying data source to associate observations with their related dynamic entities.

The following field types are supported for the entity id field: FieldType.int16, FieldType.int32, FieldType.int64, FieldType.float32, FieldType.float64, FieldType.guid, FieldType.oid, FieldType.globalId, and FieldType.text.
