repeater嵌套问题...

页面代码:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>无标题页</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand">
<HeaderTemplate></HeaderTemplate>
<ItemTemplate><div>
    <asp:Label ID="Label1" runat="server" Text='<%# Eval("name") %>'></asp:Label></div>
      <asp:Repeater ID="Repeater2" runat="server">
      <ItemTemplate><div><%# Eval("name") %></div></ItemTemplate>
      </asp:Repeater>
</ItemTemplate>
</asp:Repeater>

    </div>
    </form>
</body>
</html>
我把Repeater1和Repeater2设置了同一个DataSet
调试页面的时候会出现.当前上下文中不存在名称Repeater2,当我把Repeater2从Repeater1中拿出来后.就能正常.有谁知道为什么吗?
--------------------编程问答-------------------- 按如下方式对 Repeater2进行数据绑定即可：

foreach (RepeaterItem item in Repeater1.Items)
        {
            Repeater r2 = (Repeater)item.FindControl("Repeater2");
            r2.DataSource = dt;
            r2.DataBind();
        } --------------------编程问答-------------------- 为什么不能直接
Repeater1.DataSource=dt;
Repeater1.DataBind();

Repeater2.DataSource=dt;
Repeater2.DataBind(); --------------------编程问答-------------------- 你要把子repeater拿出来才行.
一般在itemdatabound事件中
Repeater Repeater2;
   if (e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item)
        {
            Repeater2= (Repeater)e.Item.FindControl("Repeater2");
             Repeater2.DataSource=...
            Repeater2.DataBound();...........

} --------------------编程问答-------------------- 为什么不能直接
Repeater1.DataSource=dt;
Repeater1.DataBind();

Repeater2.DataSource=dt;
Repeater2.DataBind();

-----------------------------

嵌套之后，页面里边就不止一个Repeater2了吧
所以子Repeater的id实际上是后生成的，并不是你指定的Repeater2了。 --------------------编程问答-------------------- 嵌套之后，页面里边就不止一个Repeater2了吧 ?不明白 --------------------编程问答-------------------- 顶一下~~~~~~~~~~~~~~~ --------------------编程问答-------------------- 再顶一下..
