使用方法很简单，对于需要使用asp.net下timer控件的使用是个不错的例子

页面代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> 
<%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="cc1" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head id="Head1" runat="server"> 
<title>Untitled Page</title> 
<style type="text/css"> 
#UpdatePanel3 { 
border-right: gray 1px solid; border-top: gray 1px solid; 
border-left: gray 1px solid; border-bottom: gray 1px solid; 
width:200px; height:200px; position: relative; 
float: left; margin-left: 10px; margin-top: 10px; 
} 
</style> 
</head> 
<body> 
<form id="form1" runat="server"> 
<asp:ScriptManager ID="ScriptManager1" runat="server" /> 
<asp:UpdatePanel ID="UpdatePanel3" runat="server"> 
<ContentTemplate> 
<asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick"> 
</asp:Timer> 
<asp:Label ID="Label3" runat="server" Text="Label"></asp:Label><br /> 
</ContentTemplate> 
</asp:UpdatePanel> 
<asp:Label ID="Label4" runat="server" Text="Label"></asp:Label> 
</form> 
</body> 
</html>

using System.Web.UI.WebControls; 
using System.Web.UI.WebControls.WebParts;

using System.Threading; 
public partial class _Default : System.Web.UI.Page 
{ 
protected void Page_Load(object sender, EventArgs e) 
{ 
Label4.Text = "初始化时间：" + DateTime.Now.ToString(); 
Timer1.Interval = 1000; 
} 
protected void Timer1_Tick(object sender, EventArgs e) 
{ 
Label3.Text = "刷新时间：" + DateTime.Now.ToString(); 
} 
}
