templateId property

A system-generated unique identifier.

This can be used to query the database for specific templates. Template IDs may change when a layer is taken offline. Do not persist or cache this value. After taking a layer offline, re-query shared templates for the layer using ArcGISFeatureTable.serviceLayerId and refresh any dependent UI or caches, such as template pickers. The value is -1 for templates returned from SharedTemplateQuerySourceType.layer source.
