AspNETPager的用法

 先下载4.3版,然后安装

问题:

1.在vs.net2005中,该控件并不能自动添加到工具面板中,需要手动添加项,选定AspNetPager.dll,即可

2.在codeBehind的cs文件中,要using Wuqi.Webdiyer;

3.写好ChangePage事件后,要与aspnetpager控件相关联

以下是一段示例代码:

前台default.aspx


 <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="test_Default" StylesheetTheme="default" %>
<%@ Register Assembly="AspNetPager" Namespace="Wuqi.Webdiyer" TagPrefix="webdiyer" %>
<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:DataList ID="DataList1" runat="server">
            
<ItemTemplate>
                ProductName:
                
<asp:Label ID="ProductNameLabel" runat="server" Text='<%# Eval("ProductName") %> '>
                
asp:Label><br />

                
<br />
            
ItemTemplate>
        
asp:DataList>
        
<webdiyer:aspnetpager id="pager1" runat="server" onpagechanged="ChangePage">webdiyer:aspnetpager>     
    
div>
