UtilityNetworkAssociations | API Reference | ArcGIS Maps SDK for JavaScript 4.31

The UtilityNetworkAssociations widget class, functioning as a part of the ArcGIS Maps SDK for JavaScript, simplifies the management and manipulation of associations within a utility network. It offers an intuitive user interface, reducing the complexity of working with utility network associations. It efficiently handles associations between various utility network elements like junctions, edges, and terminals, providing precise control over the network topology. The UtilityNetworkAssociations widget class empowers developers to streamline their workflow, enhance data integrity, and enable effective network analysis and visualization within utility network applications.

Here is an example of autoRefreshAssociations set to false. UtilityNetworkAssociations-autoRefresh-false

By clicking the refresh button the associations will appear. UtilityNetworkAssociations-autoRefresh-false-manual-refresh

Here is an example of autoRefreshAssociations set to true. UtilityNetworkAssociations-autoRefresh-true

Notes

The UtilityNetworkAssociations widget class is unable to support proxied feature services or feature services that utilize stored credentials.
