将它们放在各自的面板中，pnlRadio，pnlText：

 <ul class="clearfix">
<asp:Panel id="pnlRadio" runat="server">
                    <asp:RadioButtonList ID="rbtAnswers" runat="server" RepeatDirection="Horizontal">
                        <asp:ListItem>Not At all</asp:ListItem>
                        <asp:ListItem>Fine</asp:ListItem>
                        <asp:ListItem>Average</asp:ListItem>
                        <asp:ListItem>Good</asp:ListItem>
                        <asp:ListItem>Very Much</asp:ListItem>
                    </asp:RadioButtonList>
  </asp:Panel>
<asp:Panel id="pnlText" runat="server">
                    <asp:TextBox ID="txtDesc" runat="server"  TextMode="MultiLine"/>
                </ul>

重新启用onItemDataBound然后

protected void rpt_Questions_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
    {
      DataRowView drv = (DataRowView)e.Item.DataItem;

      Panel pnlRadio = e.Item.FindControl("pnlRadio") as Panel;
      Panel pnlText= e.Item.FindControl("pnlText") as Panel;

if(drv["questionType"].ToString()=="choice") //or however you distinguish between the two
{ pnlRadio.Visible = True; pnlText.Visible = False;}
else
{ pnlRadio.Visible = False; pnlText.Visible = True;
