You can have a method in code behind for validation and call it on text changed event of the textbox or you can have a javascript validator which fires on keyup event or you can set on lost focus event.

Hope this helps

Try matching with regular expression in required event. Try this:

C#

Regex reg = new Regex("^([a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]){1,70}$");
if (!reg.IsMatch(txtEmail.Text))
{
    //Show error message.
}
else
{
   //Success.
}
