Hi,
Could you please share me demo link for validating duplicate record insertion.
1. when user will click on the add button after that a new line in grid will be added after that user will fill all the record and click on update button.
2. Now value from response is -1 and I want to show message to the user that "Record already exists".
3. User can change the value from the same grid line and update again.
Tnx
