Trying to validate a comma-separated email list in the textbox with asp:RegularExpressionValidator
, see below:
<asp:RegularExpressionValidator ID="RegularExpressionValidator1"
runat="server" ErrorMessage="Wrong email format (separate multiple email by comma [,])" ControlToValidate="txtEscalationEmail"
Display="Dynamic" ValidationExpression="([w+-.%]+@[w-.]+.[A-Za-z]{2,4},?)" ValidationGroup="vgEscalation"></asp:RegularExpressionValidator>
It works just fine when I test it at http://regexhero.net/tester/, but it doesn't work on my page.
Here's my sample input:
[email protected],[email protected]
I've tried a suggestion in this post, but couldn't get it to work.
p.s. I don't want a discussion on proper email validation
