子控件获取父控件ID1
现在我有一个checkbox在datalist里，想再点击checkBox时在后台获得datalist 的ID。该怎么弄？以checkbox chk =（checkbox）sender，为前提找
求大神指导

[解决办法]
CheckBox chk =（CheckBox ）sender;
chk.Parent或者chk.Parent.Parent去找，

HTML code

<%@ Page Language="C#" EnableViewState="true" AutoEventWireup="true" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><script runat="server">  protected void Page_Load(object sender, EventArgs e)  {    if (!Page.IsPostBack)    {      System.Data.DataTable dataTable1 = new System.Data.DataTable();      dataTable1.Columns.Add(new System.Data.DataColumn("ID", typeof(System.Int32)));      dataTable1.Columns.Add(new System.Data.DataColumn("Title", typeof(System.String)));      dataTable1.Rows.Add(new Object[] { 1, 22, });      dataTable1.Rows.Add(new Object[] { 2, 2222 });      dataTable1.Rows.Add(new Object[] { 3, 22222 });      DataList1.DataSource = dataTable1;      DataList1.DataBind();    }  }  protected void chk_CheckedChanged(object sender, EventArgs e)  {    CheckBox chk = sender as CheckBox;    DataList d = chk.NamingContainer.Parent as DataList;    Response.Write(d.ID);  }</script><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server">  <title></title></head><body>  <form id="form1" runat="server">  <asp:DataList ID="DataList1" runat="server">    <ItemTemplate>      <asp:CheckBox ID="chk" runat="server" AutoPostBack="true" OnCheckedChanged="chk_CheckedChanged" /><%#Eval("Title")%>    </ItemTemplate>  </asp:DataList>  </form></body></html>
