  create user wizard email validation

  Apr 04, 2012 02:44 AM|LINK

  Hi,

  It seems that this wizard does not automatically validate an email address.  There is a property setting for a regular setting that should accomplish this task but I can't get anything to work there.  I've copied a number of regular expression for email validation from various internet sources, but I always get a runtime exception.  It would seem that this is a very common problem and there probably is a simple solution - but, I can't find it!

  I assume this property was established as a simple way to address this common need - is there a regular expression that can be plugged into this property that will catch an invalid email address and give the user a change to correct it?

  Try this expression validator on your aspx page:
  
  <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"
  ControlToValidate="EMAIL TEXT ID HERE" ErrorMessage="RegularExpressionValidator"
  ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"></asp:RegularExpressionValidator>

  Substitute EMAIL TEXT ID HERE with the name of your wizard's email textbox ID.

  Please try this.

  <asp:createuserwizard id="Createuserwizard1" runat="server"         emailregularexpression='@"^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$"'         emailregularexpressionerrormessage="E-mail address must be in a valid format">       </asp:createuserwizard>

  Try this expression

  "\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"

  Hi,

  Thanks to all of you - this is a great forum for help!

  I combined two of the suggestions to get this

  emailregularexpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"        emailregularexpressionerrormessage="E-mail address must be in a valid format" 

  I'm also happy to report that it properly understood somename@wi.rr.com which is sometimes rejected by some validations because of the double periods.

  for some reason this one rejected every email address:

   emailregularexpression='@"^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$"'

  I should also try the suggestion from Olivespike, but I wasn't quite sure where to find "your wizard's email textbox ID" - I suspect one needs to expand the templates.

  Right now things look good - however, I still need to figure out how to deal with the fact that clicking the create button only clears the email error and does not fire the registration process until clicked again - that is going to cause confusion.

  Thanks very much

  Hi,

  I'm still having a problem.  The issue is that I don't use the security questions so the last textbox is for email.  The regular expression works great at catching invalid emails.  However, the scenario is: the user enters an invalid email address and is warned with an error message.  Then the user corrects the email address and clicks "create user".  This causes the error message to disappear but nothing else happens and the user just sits there thinking that "this is taking a really long time - something must be wrong".  Maybe they click "create user" again - maybe not.  This is not a good situation.

  I've been trying to figure out how to determine that the error was fixed (when the user clicks "create user" and then actually fire the "create user" process.  Or, somehow, tell the user that the email is now OK and click "create user" again.  I've tried all the events in my code behind but nothing seems to address this problem.  The "createUserError" event does not make sense to me - I never see it fire.  The "creating user" does not fire just because the user clicked the button.  I really need to know that the user has clicked this button and then understand if an error is fixed or not.  If the error is fixed then how to move on with the actual create user process.

  Actually, I'm having a lot of trouble trying to understand the template model as it relates to this problem.  I looked at some tutorials but nothing seems to get at this issue.

  in "create user" event add this

  if(Page.IsValid)
              {
                  //implement your code
              }

  this property will return true, if page validation succeeded

  Thanks 2pac for the reply.

  The problem is that I never see any of these events the first time the user clicks "create user" after he has fixed his email:

   Protected Sub CreateUserWizard1_CreatingUser(sender As Object, e As System.Web.UI.WebControls.LoginCancelEventArgs) Handles CreateUserWizard1.CreatingUser

          MsgBox("creating user")

   End Sub

  Protected Sub CreateUserWizard1_CreatedUser(sender As Object, e As System.EventArgs) Handles CreateUserWizard1.CreatedUser

          MsgBox("created user")

    End Sub

    Protected Sub CreateUserWizard1_CreateUserError(sender As Object, e As System.Web.UI.WebControls.CreateUserErrorEventArgs) Handles CreateUserWizard1.CreateUserError

          MsgBox("creating user error")

    End Sub

  I don't see the first two messages until the user clicks the create user button the second time (if they actually do).  And, I never see that third "createUserError" message.

   

  So, how can I tell that the user clicked that "create user" button for any reason?  How can I wire an event just to that button itself?

  Thanks.

  Perhaps you're missing FinishDestinationPageUrl; such as:

  <asp:CreateUserWizard ID="CreateUserWizard1" runat="server" FinishDestinationPageUrl="~/pagetogotonext.aspx">
