Question

求C#自动生成控件的样例，急~~~

求一个C#自动生成控件的样例，最好带有从数据库中读取信息的，要完整的代码，因为要做项目，初学不会，还请大家帮助
是个自定义控件，里面的例如按钮啥的，是通过代码的编写生成的，并不是手动直接加载的

Answer 1

vs自动生成的就是咯。。

components.Dispose();
}
base.Dispose(disposing);

Answer 2

你可以在百度上搜“动态控件”或者是“代码控件”，下面一段程序是关于动态添加按钮的，需要编写者在windows应用程序中手动先添加静态的一个按钮（将其id属性设为btn）和一个文本框（id=txt_msg）。随后双击窗体form，于后台复制如下代码，F5运行。

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

namespace WindowsApplication9
{
public partial class Form1 : Form
{

private void Form1_Load(object sender, EventArgs e)
{

}

private int count = 0;//用于计数，添加了多少个按钮
public Form1()
{
InitializeComponent();
}

private void btn_addButtons_Click(object sender, EventArgs e)
{
//计数，计算目前是添加的几个按钮
count++;
//计算待添加按钮的位置
int localY = this.btn_addButtons.Height * count;
int localX = 10 * count;
Button toAddButton = new Button();
//设置待添加按钮的属性
toAddButton.Name = "Button " + count;
toAddButton.Text = "按钮 " + count + " ";
toAddButton.Location = new Point(localX, localY);
//设置添加按钮的事件
toAddButton.MouseEnter +=
new System.EventHandler(this.btn_MouseEnter);
toAddButton.MouseLeave +=
new System.EventHandler(this.btn_MouseLeave);
toAddButton.Click += new System.EventHandler(this.btn_Click);
//把控件添加到窗口中
this.Controls.Add(toAddButton);

}

private void btn_MouseEnter(object sender, System.EventArgs e)
{
//unboxing
Button currentButton = (Button)sender;
//设为鼠标的背景颜色
currentButton.BackColor = Color.White;

}

private void btn_MouseLeave(object sender, System.EventArgs e)
{
//unboxing
Button currentButton = (Button)sender;
//设为鼠标的背景颜色
currentButton.BackColor =
System.Windows.Forms.Control.DefaultBackColor;

}

private void btn_Click(object sender, System.EventArgs e)
{
//unboxing
Button currentButton = (Button)sender;
//显示单击了哪个按钮
txt_msg.Text = "你单击了" + currentButton.Text;

}

}
}

Answer 3

思想是：先用实例化类的方法，实例化一个空间，在主控件添加就行了
比如在打开页面，或者窗体的时候，在panel上新建一个按钮，在Page_Load()或者FormLoad()中添加如下代码
Button Btn=new Button();
//配置下按钮的属性
panel.controls.add(Btn);
