c# - 如何从同一中继器项目中的下拉列表中选择的更改事件中获取中继器项目中控件的值？

Question

<ItemTemplate>
   <tr class="odd gradeX">
      <td>
         <%#Eval("Caption")%>
      </td>
      <td>
         <%#Eval("CreatedBy")%>
      </td>
      <td>
         <%#Eval("CreationDate")%>
      </td>
      <td>
         <%#Eval("Status")%>
      </td>
      <td class="center">
         <div class="controls center">
            <a href="NewsCommentEdit.aspx?mtid =<%#Eval("UserId")%>" title="Güncelle" class="tip">
               <span class="icon12 icomoon-icon-pencil"></span>
            </a>
         </div>
      </td>
      <td>
         <asp:HiddenField runat="server" ID="hdnComment" Value='<%#Eval("NewsCommentId")%>' />
         <asp:DropDownList runat="server" ID="ddlStatus" AutoPostBack="True"  OnSelectedIndexChanged="ddlStatus_Changed">
            <asp:ListItem Text="Onay Bekliyor" Value="0"></asp:ListItem>
            <asp:ListItem Text="Onaylandı" Value="1"></asp:ListItem>
            <asp:ListItem Text="Reddedildi" Value="2"></asp:ListItem>
         </asp:DropDownList>
      </td>
   </tr>
</ItemTemplate>

我想在ddlStatus的选定索引更改事件中获取hdnComment的值。这可能吗？如何实现？

Answer 1

    protected void ddlStatus_Changed(object sender, EventArgs e) 
    {
        string value;
        HiddenField comment = ((Control)sender).Parent.FindControl("hdnComment") as HiddenField;
        if (comment != null) 
        {
            value = comment.Value;
        }
    }
