Hi Ben,
Greetings from Syncfusion support.
We checked this scenario by creating a sample to refresh Grid’s row data using SetRowDataAsync method of Grid. In which, we could refresh a row even without enabling Grid’s inbuilt editing feature. We are attaching the sample for your convenience, please download the sample from the link below,
Kindly refer the above sample and use the Grid’s SetRowDataAsync method to programmatically refresh a particular row in Grid. If we have misunderstood your requirement or if you are still facing difficulties then kindly share with us a simple issue reproducing sample along with a video demo explaining your complete requirement to proceed further.
Regards,
Renjith R
