Dear FriendsI want to add a little code that when a user is trying to register in portal and click on Register it happen .Because I'm beginner , I don't know how can I add my code to Register (.JS) button?I cant find a part that handle click event on Register Button in my CodeBehind.VBKindly please help know where should i put my extra VB code, to happen when user is registered in portal.Many Thanks

Many Thanks For your Guide !

But i think some miss understanding happen, i meant register button on (down part of page), let me enplane the event :
When some one new , register in the web site and after that user name and password send to him/her, i want to add some code there , it means after user registration is finished.
Kindly please tell me the .ascx file that deal with this email sending , then i can simply put my new code there.

Many Many Thanks
