急！前台服务控件在后台无法找到！

Question

 急！前台服务控件在后台无法找到！不是没有server哈，是有的 也没改过什么！一个拖的是服务控件text  一个拖的是html控件 然后加入了  runat="server"奇怪的是这两个控件都找不到！我前面有个服务控件lable也是找不到，但是我用这种方法把他找到了：
if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
        {
           lbl = (Label)(e.Item.FindControl("Label1"));
           
        }但是前面两个用这种方法就不行！！急需解决ok就给分，谢谢了！关键代码：
html<div id="hf+<%# Eval("lybh")%>" style="display:none; border:1px solid black; width:254px; text-align:center">
                                          
                                            <table>
                                                
                                                <tr>
                                                    <td align=right>昵称：</td>
                                                    <td>
                                                    
                                                        <asp:TextBox ID="TextBox1" runat="server"  Width="175px"></asp:TextBox></td>
                                                </tr>
                                                <tr>
                                                    <td  align=right>内容：</td>
                                                    <td>
                                                    <textarea id="TextArea1"  cols="20" rows="2" runat="server" style=" height:170" ></textarea></td>
                                                </tr>
                                                <tr>
                                                    <td colspan="2" align=center>
                                                        <asp:Button ID="Button1" runat="server" Text="确定" OnClick="Button1_Click" />
                                                    
                                                        <input  type="button" id="<%# Eval("lybh")%>" value="取消" onclick="qx(this)" /></td>
                                                </tr>
                                            </table>
                                            
                                        </div>
后台：protected void Button1_Click(object sender, EventArgs e)
    {
       
        TextBox nmd = (TextBox)(RepeaterPage.FindControl("TextBox1"));
      //  TextBox nm = (TextBox)( Repeater2.ItemTemplate.InstantiateIn("TextBox1"));
        TextBox nr = (TextBox)(Master.FindControl("TextArea1"));
      TextBox cc= (TextBox) this.Repeater2.FindControl("TextBox1");
        Response.Write("<script>alert('资料有误!');</script> "); 
    }写法都是不成功的！

Answer 1

是在repeater控件中吗
protected void Button1_Click(object sender, EventArgs e)
        {
            RepeaterItem item  =(RepeaterItem) ((Button)sender).Parent;
            Label l = (Label)item.FindControl("lbl");
            Response.Write(l.Text);
        }

Answer 2

如果是放在数据集控件中需要使用findcontrol方法来寻找！

Answer 3

我不是要中哦啊lable的值！那个值我已经取到了，是那个textb 和 textarea 这两个都找不到！！！！！

Answer 4

如梦老大已经说得很清楚了啊RepeaterItem item =(RepeaterItem) ((Button)sender).Parent;
Label l = (Label)item.FindControl("lbl");蓝色是找到Repeater的行。
红色是用这一行来找控件
你要找TextBox 还是 TextArea1  自己换一下不就完了
