让DataList分页
DatList 默认情况下好像不支持分页，今天尝试了一下，也让DatList能分页。给象我一样的初学者参考，希望能起到举一反三的效果。
aspx代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>panboxian test page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:DataList ID="DataList1" runat="server">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text="<%# bind('id') %>"></asp:Label><br />
<asp:Label ID="Label2" runat="server" Text="<%# bind('id') %>"></asp:Label><br />
<asp:Label ID="Label3" runat="server" Text="<%# bind('id') %>"></asp:Label>
</ItemTemplate>
</asp:DataList>
<asp:Label ID="lblPageCount" runat="server"></asp:Label><br />
</div>
</form>
