Validation of emails

[Stephen]

Hi,

Can someone give me suggestions on how to validate emails that are entered
into a textbox?
the problem is that they can enter any number of emails say the textbox is
called Notificationlist and has 10 email addresses, i need to read this and
validate all the emails before inserting into the DB

thanks,
Stephen

You can use RegularExpressionValidator.

<asp:RegularExpressionValidator id="Regularexpressionvalidator"
runat="server"
ControlToValidate="txtEmail"
ValidationExpression="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*([,;]\s*\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*)*"
ErrorMessage="<br>* Check email"
CssClass="alert"
ForeColor=""
display="dynamic">
</asp:RegularExpressionValidator>

The specific validation expression lets you enter a list of emails
separated by comma or semicolon. When it's validated, you can split it
up into individual email addresses and you're good to go.

Hope it helps,
Amie
