/* 自定义控件*/

创建自定义控件

BLL层中的Hello.cs:

using System;

using System.Web.UI;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Text;

using System.Windows.Forms;

namespace BLL

{

public partial class Hello : System.Web.UI.Control

{

/*在BLL层右键Add---〉CustomControl会自动产生下面的一个构造器

* 和一个OnPaint方法---〉怀疑和using System.Windows.Forms;有关

//public Hello()

//{

// InitializeComponent();

//}

//protected override void OnPaint(PaintEventArgs pe)

//{

// // TODO: Add custom paint code here

// // Calling the base class OnPaint

// base.OnPaint(pe);

//}

protected override void Render(HtmlTextWriter writer)

{

//base.Render(writer);

writer.Write("Hello,baby!");

}
