Add features

Add features to a feature layer.

Use case

An end-user performing a survey may want to add features to the map during the course of their work.

How to use the sample

Tap on a location on the map to add a feature at that location.

How it works

A Feature instance is added to a ServiceFeatureTable which then pushes that new feature to the server.

1. Create a ServiceGeodatabase from a URL.
2. Get a ServiceFeatureTable from the ServiceGeodatabase.
3. Create a FeatureLayer derived from the ServiceFeatureTable instance.
4. Create a Feature with attributes and a location using the ServiceFeatureTable.
5. Add the Feature to the ServiceFeatureTable.
6. Apply edits to the ServiceGeodatabase which will upload the new feature to the online service.

Relevant API

• Feature
• FeatureEditResult
• FeatureLayer
• ServiceFeatureTable
• ServiceGeodatabase

Additional information

When editing feature tables that are subject to database behavior (operations on one table affecting another table), it's now recommended to call these methods (apply edits & undo edits) on the ServiceGeodatabase object rather than on the ServiceFeatureTable object. Using the ServiceGeodatabase object to call these methods will prevent possible data inconsistencies and ensure transactional integrity so that all changes can be commited or rolled back.
