In this article I will show you that how you can validate the controls which are inside the Grid View control.

User ID = @User ID) AND (Delete = 0)" Insert Command="INSERT INTO tbl User(First Name, Last Name, User Name, Password, Birthdate, Address, Apt, City, Province, Postal Code, Email, Phone Num, yn Admin User, yn Delete) VALUES (@First Name, @Last Name, @User Name, @Password, @Birthdate, @Address, @Apt, @City, @Province, @Postal Code, @Email, @Phone Num, @yn Admin User, 0)" Update Command="UPDATE tbl User SET First Name = @First Name, Last Name = @Last Name, Birthdate = @Birthdate, Address = @Address, Apt = @Apt, City = @City, Province = @Province, Postal Code = @Postal Code, Phone Num = @Phone Num, Email = @Email, yn Admin User = @yn Admin User WHERE (User ID = @User ID)"it's throwing an exception because it's trying to pass NULL as the province parameter...which indicates that ddl Province.

According to the above, in these three operations we use three events of the Grid View for each operation.For this I will make the editable Grid View and use the Required Field Validator for the Text Boxes.
