Update geometries (feature service)

Update a feature's location in an online feature service.

Use case

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

How to use the sample

Tap a feature to select it. Tap again to set the updated location for that feature. An alert will be shown confirming success or failure.

How it works

1. Create a ServiceFeatureTable object from a URL.
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.
