Use case

Online feature services can be updated with new data. This is useful for updating existing data in real time while working in the field.

How to use the sample

To change the feature's damage property, tap the feature to select it, and update the damage type using the drop down.

How it works

Create a ServiceFeatureTable object from a URL.
- When the table loads, you can get the domain to determine which options to present in your UI.
Create a FeatureLayer object from the ServiceFeatureTable.
Select features from the FeatureLayer.
To update the feature's attribute, first load it, then use the SetAttributeValue.
Update the table with UpdateFeatureAsync.
After a change, apply the changes on the server using ApplyEditsAsync.
