Hi Pravin,
I think what Pvsb prasad k meant is you remove the blank record after the user pressed the add button.
You would do normally as per what you have done when user enter the data (Add a blank row for user to key in).
When the user is trying to 'ADD' the record into database, you should catch on before data add event, check your last row and remove as necessary.
Regards
