十一假期还没怎么过就过完了
为啥放假总是过地这么快呢...
哎，又开始了天天和电脑搏斗的生活了...
上网偶然发现AJAX Control Toolkit在上个版本发布4个月后，9月30又更新了
这次更新了2个控件：
- SeaDragon - This version of Seadragon allows you to display an image, and to zoom in and out of that image using mouse button keys without resizing the window.
- AsyncFileUpload - This new control enables you to perform file uploads without doing a postback. The control displays a throbber image during upload and raises client and server events when the upload is complete. This control was contributed by Steven Lindsay.
详细请看：http://ajaxcontroltoolkit.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=33804
AsyncFileUpload ，顾名思义，就是上传文件了，贴图看下效果：
事件，属性和方法：
SeaDragon 是个挺好玩的东西哦，看名字眼熟吧，它就是来自微软的在线图片服务Seadragon（http://livelabs.com/seadragon/），连名字都一摸一样哦
其实仔细看看有点类似deepzoom，不过不是用silverlight,而是用了AJAX（感觉还是Silverlight效率高啊，其实最新的Deep Zoom Composer也已经支持导出AJAX的图片了，上回就说等有时间写写Deep Zoom Composer，看来还得下次再写了... ）
看图看效果：
