Email validation in grid

[John]

Hi

Is there anyway to validate an email address when typed in a field in grid
to stop people from entering invalid email addresses? Is there a way to do a
reverse dns lookup as well?

Thanks

Regards

Hi,

I would use a regular express to check if you have a valid email

Dim regEmail As New
System.Text.RegularExpressions.Regex("^((???:[a-zA-Z0-9][\.\-\+_]?)*)[a-zA-Z0-9])+)\@((???:[a-zA-Z0-9][\.\-_]?){0,62})[a-zA-Z0-9])+)\.([a-zA-Z0-9]{2,6})$")
Trace.WriteLine(regEmail.IsMatch("test.com"))
Trace.WriteLine(regEmail.IsMatch("(e-mail address removed)"))
