If the form will only be filled out once by the user and there are only a couple of numbers, it doesn't really matter which format you pick.I would strip the formatting out before storing it in the database. If a lot of phone numbers are going to be entered by each user, I'd lean towards unformatted entry.Net control's values in variables so it cannot be repeated again and again in our function the email Exp variable holds the pattern of the email id in the form of a regular expression.Now add the condition to ensure that all controls have a value, if the values are not entered in the form control then it will show a message.
