Use case

Sometimes users may want to edit features in an online feature service by moving them.

  2. Create a FeatureLayer object from the ServiceFeatureTable.
  3. Select a feature from the feature layer, using FeatureLayer.SelectFeatures.
  4. Load the selected feature.
  5. Change the selected feature's location using Feature.Geometry = geometry.
  6. After the change, update the table on the server using ApplyEditsAsync.
