Hi,

I have an TextBox control on my WebForm and I need to validate it to ensure it isn't an email address. I know how to use a RegEx validator to check IT IS an email address but how would I validate it to check it IS NOT an email address?

Thanks in advance.

Hi AndyBanks

Please refer to this article:   http://www.codetoad.com/asp_email_reg_exp.asp. It uses Pattern to find out if the test is a regular expression. You can write a custom validator and then give an error message if the text contains an email pattern.

You can also try using Reg Expression Validator and add !  (not) infornt of the regular expression for the email. I have not tried this but it may work.
