前台调用(ASPX):
<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>
<%@ Register TagPrefix="wo" Assembly="MyControl" Namespace="MyControl" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.

<body>
    <form id="form1" runat="server">
    <div>
    <wo:MyButton Types="Button" Text="aa" id ="Button1" runat="server"  OnClick="Button1_Click"/>
    </div>
    </form>
</body>
</html>
aspx.cs文件:
using System;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        this.Button1.Click+=new EventHandler(Button1_Click);
    }

    protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Write("<script>alert('aa')</script>");
    }
}
