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

<!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>无标题页</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="Button" />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox1"
ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator></div>
</form>
</body>
</html>

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class test : System.Web.UI.Page
{

protected void Page_Load(object sender, EventArgs e)
{
Button1.Click += new EventHandler(Button1_Click);
}

protected void Button1_Click(object sender, EventArgs e)
{
Page.RegisterStartupScript("su", "<script language=javascript>alert('click');</script>");
}
}

<asp:Button ID="Button1" runat="server" Text="Button" />在页面中我们就可以不用声明他的单点击件是哪个,就可以在页面加载事件中动态的为它指定,,尽量让美工与后台的程序脱离.同时也理解了理件的一点机制
