Hi Saipavanchandu,
Accoridng to your description, I couldn't understand your requirement clearly.
Does your grdiview contains multiple row in it?
Do you mean you want to add the textbox value to each row's dropdownlist?
Do you write some codes according to your requirement? Have face any issue?
If you could post more details information, it will be more easily for us to understand your requirement and give you a solution.
Best Regards,
Brando
