散分，后天结贴，顺便学习下web自定义控件的制作步骤

演练：创建 Web 自定义控件

1、打开vs
2、在解决方案资源管理器中右键单击—添加—新建项
3、选择Web用户控件
4、单击添加按钮。
5、打开新建的那个后缀名ascx的文件。
6、编辑(随便画几个表格，弄张图片)。
7、保存。
8、这时，一个用户自定义控件就算做好了，可以把刚才新建的文件（控件）随意拖到想用的地方。

写自定义控件首先在先建项目和先选择 web ，再选asp.net 服务哭控件

写自定义控件首先在新建项目时先选择C# 中的 web ，再选asp.net 服务哭控件就可写自定义控件了

研究控件源码QuickPager

aspnetpager源码找了好久，都睛DEMO源码，dll的源码没找到啊~！
还有，有变动，我后天才能上车，所以贴子要大后天才能结~！

1.新建一个派生自WebControl的类，
2.重写Render(HtmlTextWriter writer)实现功能，
3.编译成类库
4.在应用的工程的工具箱内添加选择项，拖进页面就行了，系统会自动注册控件的

maek 了顺便帮楼主顶上去

说原理难  毕竟微软公布的源码不多
只不过是继承一些微软些好的软件然后加功能  改写下等等...
