Trying to validate a comma-separated email list in the textbox with \[code\]asp:RegularExpressionValidator\[/code\], see below:\[code\]<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>\[/code\]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:\[code\][email protected],[email protected]\[/code\]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
