ASPxTextBox - Add Email address format validator

Hello Duke:
Yes, the built-in regex validator allows validating emails.
Moreover, you can set a corresponding regular expression automatically when you select it from the list of pre-defined patterns.
I have attached screencasts that illustrate how to accomplish this task.
Thanks
Kate.

Hi Kate,
Thanks for the reply…
I'm not seeing the same experience you're showing me… I'm accessing the Properties editor in source view as my textbox control is in a gridview edit form.
Here is the code that I had to implement in order to validate a required email and email address format. Note that I had to enter my own regular expression.
                                                <dx:ASPxTextBox ID="tbxEmail" Text='<%# Bind("Email") %>' ErrorDisplayMode="Text">
                                                    <ValidationSettings SetFocusOnError="True" ValidationGroup="EditForm" Display="Dynamic" ErrorTextPosition="Bottom">
                                                        <RequiredField IsRequired="True" ErrorText="Required" />
                                                        <RegularExpression ErrorText="Invalid Email Format" ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*.\w+([-.]\w+)*" />
                                                    </ValidationSettings>
                                                </dx:ASPxTextBox>
QUESTION: How do I implement an email validator as you recommend?
Thanks,
-Duke

Hello Duke:
The attached markup illustrates that you have already implemented the regex email validation for the ASPxTextBox and your regular expression looks correct.
Unless I am mistaken, you use this textbox in the EditFormTemplate container of the ASPxGridView. Please take a look at the following article to learn more how to execute automatic validation of the customized edit form when you click Update:

Your feedback is highly appreciated.
Thanks
Kate.
