Can you give some code of your html file where reg. expression is?

<asp:TextBox ID="txtEmailid" runat="server" Width="180px" BorderColor="Black"
BorderStyle="Solid" BorderWidth="1px" >
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="txtEmailid" ErrorMessage="Invalid" ForeColor="#F04E23"
ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*">

Hi,
1. your regex expression is correct so, try to check your input email address.
2. If it doesn't work in client side, check with page side validation in c#.
3. If page side validation works fine, try to create new text box with new regex validation control

did you checked the validation group if any ?

I didn't use any javascript. I used RegularExpression validator control which is in asp.net

The validation control uses javascript or something on the client side.

You should make a validation group, called form or something, and add the validation group attribute to the textbox, validation control and submit button, and add causes validation to the submit button.

On the code behind, I think it's, I write in VB, so it's a little different in CS

If Page.validation then

end if

Clear your browser cache and test it. Check your version of asp.net on the server, it may be out of date, or IIS web server may have to be restarted, it may be caching html, and the cache didn't update.
