Can you please provide some links to the documentation? Thanks!
Hello jdymond,
The API page for the WebHierarchicalDataGrid's ClientEvents property is here.
In general, you can find out about the WebHierarchicalDataGrid's CSOM (Client Side Object Model) here.
The API overview is here.
The CSOM and API are automatically generated from the code. If these are not helpful, you can always post a specific question to the forums. If you'd like to see a specific topic written about a common scenario, you can click on the link at the top of each help page (Email your feedback on this topic).
