Hi Cristiano,
Thanks for contacting Syncfusion support.
Based on your query that the Grid is not refreshed with new data after adding and updating the records in Grid. Before we proceed with your query, we need the following details
1. Share the Grid code example.
2. Have you used any adaptors(URL, remoteSave, WebAPI etc.,) in your sample?
Regards,
