I created a array list and added the username and password in it
And concadinated those two values seperated by comma and stored in a string vriable and passed the string to the DB(For avoiding multiple round trip). It works perfectly for the username and password verfication.
But the requirement is to validate multiple text box in server side, When i go for the same approach for this DB doesn't know Which control holds what value and while returning back am facing control mapping problems.
Please do the needful
