Carroll <Click here to reveal e-mail address> -- Hi All, I am writing validation for an email address. First off, i want to make sure there isn't a problem using 2 RegularExpressionValidator's for one field.... Other than that this is what I have, the first works fine, but the second, where I'm trying to exclude ":", I can't figure out the syntax.... <ASP:textbox id="email" Text="" size="32" runat="server" /> <asp:requiredFieldValidator id="ValRequired1" runat="server" ControltoValidate="email" Display="dynamic">* You must enter an Email Address.</asp:requiredFieldValidator> <asp:RegularExpressionValidator id="ValRequired2" ControlToValidate="email" Display="Dynamic" ValidationExpression=".+[@].+[.].+" runat="server"> <br>*Invalid Email Address </asp:RegularExpressionValidator> <asp:RegularExpressionValidator id="ValRequired3" ControlToValidate="email" Display="Dynamic" ValidationExpression=".+[^:].+" runat="server"> <br>*Can Not Contain /:,; </asp:RegularExpressionValidator> I have also tried... ".*[^:].*" "[^:]" "[^\:]" Thanks Rel PS> my next step will to be sure to exclude "/", ";" and "," how do you exculde more than 1 character with 1 expression? Reply to this message...        Steven A Smith (VIP) 1. You can use as many validators of any type for a given ControlToValidate as you like. 2. There are several excellent email validation expressions that actually validate to the email RFC standard at http://regexlib.com/, so if you're not doing this as a personal exercise to learn regular expressions, you might look there.
