        RadioBut.Items.Add("問答題")
        RadioBut.RepeatDirection = RepeatDirection.Horizontal
        PlaceHolder1.Controls.Add(New LiteralControl(" <td width=30%>"))
        PlaceHolder1.Controls.Add(RadioBut)
        PlaceHolder1.Controls.Add(New LiteralControl(" </td>"))
        PlaceHolder1.Controls.Add(New LiteralControl(" <tr>"))
