先是aspx页面

<asp:Repeater ID="rp" runat="server">
<ItemTemplate>
<%# Eval("id") %>
<asp:Repeater ID="rp1" runat="server" DataSource='<%# GetData(Eval("id")) %>'>
<ItemTemplate>
<%# Eval("name") %><br />
</ItemTemplate>
</asp:Repeater>
<br />
</ItemTemplate>
</asp:Repeater>

其中关键是<asp:Repeater ID="rp1" runat="server" DataSource='<%# GetData(Eval("id")) %>'>
GetData是一个自义函数,原型如下:

protected DataTable GetData(object obj)
{
DataTable dt = new DataTable();
//这里做一些事情
return dt;
}

完整的代码如下:aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="test.aspx.cs" Inherits="test" %>
<%@ Import Namespace="System.Data" %>

<ItemTemplate>

<asp:Repeater ID="rp1" runat="server" DataSource='<%# GetData(Eval("id")) %>'>
<ItemTemplate>
<%# Eval("name") %><br />
</ItemTemplate>
</asp:Repeater>
<br />
</ItemTemplate>
</asp:Repeater>
