Remove RequiredFieldValidation from GridView Row

Question

I have a Gridview like excel sheet. I use it to update and insert new records. The last row is used for insertion and can be empty. I need to add RequiredFieldValidation for when rows are updated or inserted but I want to remove it when the whole row is empty. How can this be implemented.

Thank you for your suggestions :)

Row1 [WithValdations] Row N [No Validations when Empty]

Answer 1

If the validators are added with Id's you can reference those Id's from code, and turn the validators on and off programmatically.
