I have a text box that is intended for an Email address. I am using a Regular eExppression validation control to validate the email address.

When I place the following lines of code in a blank web Form, the validator works properly.

<pre lang="c#"><asp:TextBox ID="Email" runat="server" CssClass="DefaultTextBox TextboxWidth" MaxLength="80"></asp:TextBox>

<asp:RegularExpressionValidator ID="valEmail" runat="server" ControlToValidate="Email" ErrorMessage="Invalid Email address" SetFocusOnError="True" ToolTip="Invalid Email address" ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*">*</asp:RegularExpressionValidator`>

However, when I use the validation control within a CreateUserWizard control, it does not seem to fire but other validation controls (Required and Custom validators) do fire, but not the regular expression validator above for validating the address. I

When i click on create_user button validator removed automatically even email is not correct. and able to create user..&amp;lt;/pre&amp;gt;&lt;/pre&gt;</pre>
