For the validation of the email we have the default rule on the property. Go to the property and in the advanced tab we have the coloumn called the edit validate option in that if you click the dropdown we will find many rules in that choose the valid email address.Click on that. While at the run time it will validate the email address property. If you want to customize the rule means save it in your rule set with the lable and you can change the code.
