Hi Venkaiah,
Thank you for your interest in Syncfusion products.
To save the modified data from grid to sql you can use “adapter.Update(dataset)”. You can use this inside the CurrentCellAcceptedChanges().This event Occurs when the grid accepts changes made to the active current cell. Kindly refer the below provided code snippet for further reference.
Code Snippet:
this.sqlDataAdapter1.Update(this.dataSet11);
Please let us know if you have any other concerns.
Thanks & Regards,
AL.Solai.
