@Prefekt I think you can get some useful info from the last few messages on my thread here https://forum.radzen.com/t/updating-a-stored-procedure-parameter/5067/4
where I had similar questions. I was referring to a Stored Procedure, but it doesn't make any difference. Invoke the data source method, and set ${result} to it (again). Note that this will re-query the database, which you usually do not want to do. Generally you'd want to use "await componentname.Reload()" to update the component instead of invoking the table again.
