首先是怎么使用MagicAjax.Net。这个其实很多人多讲过了，我这里重复一下。
首先还是新建个项目，然后添加引用：MagicAjax.dll。然后在配置文件Web.config中放入以下配置：
<httpModules>
<add name="MagicAjax" type="MagicAjax.MagicAjaxModule, MagicAjax" />
</httpModules>
这样我们就能在我们的程序中使用Ajax了。哦，对了，忘了要用ajax技术的.aspx文件中还要加上这句话：
<%@ Register TagPrefix="ajax" Namespace="MagicAjax.UI.Controls"
Assembly="MagicAjax" %>
现在就没有问题拉^_^
接着是一个简单的应用。研究一些新技术我总喜欢用一些非常简单的例子，毕竟重点是弄清楚这个技术的用法，所以例子不是很复杂。
首先是.aspx文件的代码：
<%@ Page language="c#" Codebehind="WebForm1.aspx.cs" AutoEventWireup="false" Inherits="example.WebForm1" %>
<%@ Register TagPrefix="ajax" Namespace="MagicAjax.UI.Controls"
Assembly="MagicAjax" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" >
<HTML>
<HEAD>
<title>WebForm1</title>
<meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1">
<meta name="CODE_LANGUAGE" Content="C#">
<meta name="vs_defaultClientScript" content="JavaScript">

</HEAD>
<body MS_POSITIONING="GridLayout">
<form id="Form1" method="post" runat="server">
<ajax:AjaxPanel id="AjaxPanel1" runat="server">
<asp:DataGrid id="mygrid" Runat="server"></asp:DataGrid>
<asp:Button id="Button1" style="Z-INDEX: 101; LEFT: 48px; POSITION: absolute; TOP: 192px" runat="server"
Text="确定" Width="96px" BackColor="Transparent"></asp:Button>
<asp:Button id="Button2" style="Z-INDEX: 102; LEFT: 208px; POSITION: absolute; TOP: 192px" runat="server"
Text="确定2" Width="104px" BackColor="Transparent"></asp:Button>
</ajax:AjaxPanel>
<asp:DataGrid id="DataGrid1" style="Z-INDEX: 103; LEFT: 368px; POSITION: absolute; TOP: 264px"
runat="server" Width="240px" Height="248px"></asp:DataGrid>
<asp:Button id="Button3" style="Z-INDEX: 104; LEFT: 440px; POSITION: absolute; TOP: 576px" runat="server"
Text="Button" Width="104px" Height="32px"></asp:Button>
</form>
</body>
</HTML>
MagicAjax把要实现无刷的控件放在一个AjaxPanel中。在这里，我要用按钮控制DataGrid控件的显示内容，所以我把DataGrid控件和两个Button控件放在AjaxPanel中。
<ajax:AjaxPanel id="AjaxPanel1" runat="server">
<asp:DataGrid id="mygrid" Runat="server"></asp:DataGrid>
<asp:Button id="Button1" style="Z-INDEX: 101; LEFT: 48px; POSITION: absolute; TOP: 192px" runat="server"
Text="确定" Width="96px" BackColor="Transparent"></asp:Button>
<asp:Button id="Button2" style="Z-INDEX: 102; LEFT: 208px; POSITION: absolute; TOP: 192px" runat="server"
Text="确定2" Width="104px" BackColor="Transparent"></asp:Button>
</ajax:AjaxPanel>
接下来是后台代码：
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
namespace example
{
/// <summary>
/// WebForm1 的摘要说明。
/// </summary>
public class WebForm1 : System.Web.UI.Page
{
protected System.Web.UI.WebControls.DataGrid mygrid;
protected System.Web.UI.WebControls.Button Button1;
protected System.Web.UI.WebControls.Button Button2;
protected System.Web.UI.WebControls.DataGrid DataGrid1;
protected System.Web.UI.WebControls.Button Button3;
protected MagicAjax.UI.Controls.AjaxPanel AjaxPanel1;
private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
ArrayList a = new ArrayList();
a.Add("a");
a.Add("b");
a.Add("c");
mygrid.DataSource = a;
mygrid.DataBind();
}
Web 窗体设计器生成的代码
private void Button1_Click(object sender, System.EventArgs e)
{
ArrayList a = new ArrayList();
a.Add("aa");
a.Add("bb");
a.Add("cc");
mygrid.DataSource = a;
mygrid.DataBind();
}
private void Button2_Click(object sender, System.EventArgs e)
{
ArrayList a = new ArrayList();
a.Add("aaa");
a.Add("bbb");
a.Add("ccc");
mygrid.DataSource = a;
mygrid.DataBind();
}
private void Button3_Click(object sender, System.EventArgs e)
{
ArrayList a = new ArrayList();
a.Add("e");
a.Add("f");
a.Add("g");
DataGrid1.DataSource = a;
DataGrid1.DataBind();
}
}
}
其实这个程序很简单，就是无刷新更新DataGrid控件的显示内容。为了清楚的比较刷新和无刷新的效果，我还加了个需要刷新的DataGrid控件。虽然这个刷新的速度比较快，看起来不是很明显，但你注意看的话还是发现它是刷新了的。
首先还是新建个项目，然后添加引用：MagicAjax.dll。然后在配置文件Web.config中放入以下配置：
<httpModules> <add name="MagicAjax" type="MagicAjax.MagicAjaxModule, MagicAjax" /> </httpModules><%@ Register TagPrefix="ajax" Namespace="MagicAjax.UI.Controls" Assembly="MagicAjax" %>接着是一个简单的应用。研究一些新技术我总喜欢用一些非常简单的例子，毕竟重点是弄清楚这个技术的用法，所以例子不是很复杂。
