datalist中嵌套datalist 子datalist的ItemCommand事件,该如何处理

datalist中嵌套datalist 子datalist的ItemCommand事件
我需要取得datalist中子datalist的id值.

在DataList2_ItemCommand事件中这么写


int id = Convert.ToInt32(DataList2.DataKeys[e.Item.ItemIndex].ToString());//datalist2未定义


DataList dl = (DataList)this.DataList1.FindControl("DataList2");//这里得到的dl是null
int id = Convert.ToInt32(dl.DataKeys[e.Item.ItemIndex].ToString());//未将对像引用到实例


前台:
<asp:DataList ID="DataList1" runat="server" onclick="objgetcheckbox()" GridLines="Both" HorizontalAlign="Center" DataKeyField="id" OnItemDataBound="DataList1_ItemDataBound">
            <ItemTemplate>
        <table style="width: 700px; background-color: #c8cacb;">
            <tr>
                <td style="width: 640px; text-align: left;">
                    <asp:CheckBox ID="CheckBox1" runat="server" Font-Size="12px" /><asp:LinkButton ID="LinkButton1" runat="server" Text='<%# Eval("ZS_leibiename") %>' Font-Size="12px"></asp:LinkButton></td>
            </tr>
        </table>//同事要我这里加上一个<table>试试
       asp:DataList ID="DataList2" runat="server" RepeatColumns="4" RepeatDirection="Horizontal" DataKeyField="id" OnItemCommand="DataList2_ItemCommand">
                    <ItemTemplate>
                <table style="width: 158px;">
                    <tr onmouseover="this.style.backgroundColor='#c8cacb'" onmouseout="this.style.backgroundColor=''">
                        <td style="text-align: right;">
                            <asp:CheckBox ID="CheckBox2" runat="server" Font-Size="12px" ToolTip='<%# Eval("ZS_leibieid") %>' />
                            <asp:LinkButton ID="LinkButton2" runat="server" Text='<%# Eval("ZS_leibiename") %>' Font-Size="12px" CommandName="chakan"></asp:LinkButton></td>
                    </tr>
                </table>
                    </ItemTemplate>
                </asp:DataList>
            </ItemTemplate>
        </asp:DataList>
[解决办法]
好像是e.Item.Parent.Parent吧，你调一下吧，我这里网速太慢，刷新一次csdn要n久。
