在转发器中获取DropDownList值

Question

ASPX PAGE：

 <asp:Repeater ID="GeneralRepeater" runat="server" 
 OnItemDataBound="GeneralRepeater_OnItemDataBound">
   <ItemTemplate>
     <tr>
      <td>
       DxPoc:
         <asp:DropDownList ID="GeneralDDL" DataTextField="DiagnosisCode" 
         DataValueField="DiagnosisCode" runat="server" />
     </td>
    </tr>
   </ItemTemplate>
</asp:Repeater>

背后的代码：

protected void GeneralRepeater_OnItemDataBound(object sender,
                                               RepeaterItemEventArgs e)


     {
            if (e.Item.ItemType == ListItemType.Item ||
                e.Item.ItemType == ListItemType.AlternatingItem)
            {
                DropDownList myDDL = (DropDownList)e.Item.FindControl("GeneralDDL");
                Diagnosis oDiagnosis = new Diagnosis();
                DataView dv = new DataView(oDiagnosis.GetDiagnosis());
                myDDL.DataSource = dv;
                myDDL.DataTextField = "DiagnosisCode";
                myDDL.DataValueField = "DiagnosisCode";
                myDDL.DataBind();

            }
        }

上面给出的给定不正常。在页面加载期间，它没有任何反应 转发器内的下拉列表。

问题：

a。）我将如何获得dropdownlist中包含repeater内对象列表的{{1}}的值？

谢谢！
