Connect to a service and list versions of the geodatabase.
Use case
As part of a multi-user editing scenario, you can check with the server to see how many versions of the geodatabase are outstanding before syncing.
How to use the sample
When the sample loads, a list of geodatabase versions and their properties will be displayed.
How it works
- Create a geoprocessing task referring to a GPServer with a ListVersions task.
- Use the task to create default parameters.
- Use the created parameters to create a job.
- Run the job to get a
GeoprocessingResult. - Get a list of geoprocessing features from the Versions output parameter of the results.
- Format the geodatabase versions for display.

About the data
The sample uses a sample geoprocessing service hosted on ArcGIS Online.
Additional information
ArcGIS Server does not include a geoprocessing service for listing geodatabase versions. You must configure one using the steps defined in Geoprocessing service example: list, create, and delete geodatabase versions in the ArcMap documentation.
