ASP.NET2.0: Ilungasoft.Framework.Web之基于Callback的无刷新上传进度条控件[带源码] (这个的原理跟宝玉的也是一样的，只是封装了。)
共享一个基于Callback的无刷新上传进度条控件的源码。本控件使用的HttpMoudule基于宝玉的一个上传进度条的sample，这里封装为一个控件，方便使用。无需任何代码，只需设置web.config，添加HttpModule的引用，再将控件拖到页面就行。页面中的文件保存操作和传统的asp.net文件上传完全一样。可以设置属性上传过程中出错或上传成功时跳转到其它页面。兼容IE,Firefox,Opera。其它环境没测试，不过因为是基于Asp.Net2.0的callback，其他浏览器只要支持xmlhttp或iframe就应该支持。在线演示请访问：http://teddy.cn/test
源码及示例下载
(在本机运行示例注意将程序所在目录设为对web帐号可写，否则上传文件是会权限不足报错)
下面简单列举一下示例中的web.config和Default.aspx和Default.aspx.cs。

}是不是没感觉到和使用该控件之前相比多了任何代码呢？；-）
Enjoy！
