    </asp:DropDownList>

    <asp:RadioButton ID="RadioButton2" runat="server" AutoPostBack="True" Text="Display True"

        oncheckedchanged="RadioButton2_CheckedChanged" GroupName="R1" />

 

   protected void RadioButton1_CheckedChanged(object sender, EventArgs e)

    {

        TextBox1.Visible=false;

        DropDownList1.Visible=false;
