Its very much similar what i want but the only difference is that in my case Emp name and Emp code is static but a user can add rows dynamically at client side in Field 1 , Field 2 , and Comments section so in this case how to save data( dynamically added by user ) into database.

Do I have to do use json/ajax approach or something else you suggest.

Thanks
