Как я могу контролировать переключатель в АСП .Чистая?

---

#пожалуйста, помогите мне!!
в одном списке переключателей 7, Если я выберу один переключатель, он скроет некоторое текстовое поле, а также метку также & как связать БД также я создал сохраненный proc для этого в ssms?

if (rd.SelectedValue == "Individual")
            {
                CN.Enabled = false;
                IC.Enabled = false;
                NB.Enabled = false;
                NOB.Enabled = false;
                EW.Enabled = true;
                DOI.Enabled = false;
                ITR.Enabled = true;
                PC.Enabled = false;
                AT.Enabled = false;
            }

if(rd.SelectedValue == "Individual")
{
                CN.Visible = false;
                IC.Visible = false;
                NB.Visible = false;
                NOB.Visible = false;
                EW.Visible = true;
                DOI.Visible = true;
                ITR.Visible = true;
                PC.Visible = true;
                AT.Visible = true;
}

Что я уже пробовал:

                    <asp:RadioButtonList ID="rd" runat="server"  AutoPostBack="true">
