C#动态创建控件之事件响应(刚刚答复提问,正好一并录之)

ASP:前台添加PlaceHolder

<%@ Page Title="主页" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"
    CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>






    

        欢迎使用 ASP.NET!
    
    

        若要了解关于 ASP.NET 的详细信息，请访问 www.asp.net/cn。
    
    

        您还可以找到 MSDN 上有关 ASP.NET 的文档。
    
    
     

后台代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebApplication1
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            loopshowCourse();
        }
        protected void loopshowCourse()
        {
                    Button mybutton = new Button();
                    mybutton.Text = "More";
                    mybutton.Click += new EventHandler(mybutton_Click);

                    PlaceHolder1.Controls.Add(mybutton);
        }
        protected void mybutton_Click(object sender, EventArgs e)
        {
            System.Web.UI.ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "tixin", "alert('该文件不存在或路径错误！')", true);
        }
    }
}

WindowsForms的代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsForms测试
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            Button mybutton = new Button();
            mybutton.Text = "More";
            mybutton.Click += new EventHandler(mybutton_Click);
            mybutton.Parent = this;
        }
        protected void mybutton_Click(object sender, EventArgs e)
        {
            MessageBox.Show("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa");
        }
    }

        Form 升起提示框 = new Form();
        升起提示框.FormClosed += new FormClosedEventHandler(升起提示框_关闭);
        void 升起提示框_关闭(object sender, EventArgs e)
        {
            MessageBox.Show("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa");
        }
