well, by default my radiobuttonList have a option checked of the 4 options, and so the radiobuttonLIst_IndexChanged is called and load the right controls, here is the code:

 using System;
    using System.Data;
    using System.Configuration;
    using System.Collections;
    using System.Web;
    using System.Web.Security;

    using System.Data.SqlClient;
    public partial class editors_NewsLetterControl : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            String result;
            try
            {
                SmtpMail.SmtpServer = "smtp.gmail.com";
                MailMessage mail = new MailMessage();
                mail.To = "mail@somemail";
                mail.From = "Custom subject";
                if (RadioButtonList1.SelectedValue == "Type 1 Enquiry")
                {
                    mail.Body = "Type 1 Enquiry \n\nEmail: " + emailTextBox.Text + "\n\n" + NewsLetterTextBox.Text;



                } if (RadioButtonList1.SelectedValue == "Type 2 Enquiry")
                {
                    mail.Body = "Type 2 Enquiry\n\nName: " + nameTextBox.Text.ToString() + "\nEmail: " + emailTextBox.Text + "\n\n" + NewsLetterTextBox.Text;

                }
                if (RadioButtonList1.SelectedValue == "Type 3 Enquiry")
                {
                    mail.Body = "Type 3 Enquiry \n\nName: " + nameTextBox.Text.ToString() + "\nCompany: " + companyTextBox.Text.ToString() + "\nPhone: " + phoneTextBox.Text.ToString() + "\nEmail: " + emailTextBox.Text + "\nWebsite: " + webTextBox.Text.ToString() + "\n\nMessage:\n\n" + NewsLetterTextBox.Text;

                } if (RadioButtonList1.SelectedValue == "Type 4 Enquiry")
                {

                }

                mail.Subject = subjectTextBox.Text.ToString();
                /* Some others implementations */


        }

// This is the posible method problem....
