I'm trying to send users the activation email after they register. Everything's fine except when the user clicks the link it redirects him to the same page from where the email was send. I, however, wants to redirect him to the new page (i.e to Activation.aspx).


This is my web.config code:-

<mailsettings>
  <smtp>
    <network defaultcredentials="false" host="shadi.com" port="21" username="shadi" password="*********" />
  </smtp>
</mailsettings>

What I have tried:

This is my code in C# :-

private void SendActivationEmail(int userid)
   {
       string activationCode = Guid.NewGuid().ToString();
       using (SqlConnection con = new SqlConnection(ConfigurationManager.AppSettings["str"]))
       {
           using (SqlCommand cmd = new SqlCommand("INSERT INTO UserActivation VALUES(@UserId, @ActivationCode)"))
           {
               using (SqlDataAdapter sda = new SqlDataAdapter())
               {
                   cmd.CommandType = CommandType.Text;
                   cmd.Parameters.AddWithValue("@UserId", userid);
                   cmd.Parameters.AddWithValue("@ActivationCode", activationCode);
                   cmd.Connection = con;
                   con.Open();
                   cmd.ExecuteNonQuery();
                   con.Close();
               }
           }
       }

       using (MailMessage mm = new MailMessage("shadi@gmail.com", useremail.Text))
       {
           mm.Subject = "Account Activation";
           string body = "Hello " + Convert.ToString(Session["USERNAME"]).Trim() + ",";
           body += "<br /><br />Please click the following link to activate your account";
           body += "<br /><a href="">Click here to activate your account.</a>";
           body += "<br /><br />Thanks and Regards,";
           body += "<br /><br />Shadi Team";
           mm.Body = body;
           mm.IsBodyHtml = true;
           SmtpClient smtp = new SmtpClient();
           smtp.Host = "smtp.gmail.com";
           smtp.EnableSsl = true;
           NetworkCredential NetworkCred = new NetworkCredential("shadi@gmail.com", "********");
           smtp.UseDefaultCredentials = true;
           smtp.Credentials = NetworkCred;
           smtp.Port = 587;
           smtp.Send(mm);
       }

   }

Please Help.
