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

  1. Create a geoprocessing task referring to a GPServer with a ListVersions task.
  2. Use the task to create default parameters.
  3. Use the created parameters to create a job.
  4. Run the job to get a GeoprocessingResult.
  5. Get a list of geoprocessing features from the Versions output parameter of the results.
  6. 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.
