AJAX Control Toolkit 30930

十一假期還沒怎麼過就過完了

為啥放假總是過地這麼快呢...

哎，又開始了天天和電腦搏鬥的生活了...

上網偶然發現AJAX Control Toolkit在上個版本發布4個月後，9月30又更新了

這次更新了2個控制項：

• 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.

AsyncFileUpload ，顧名思義，就是上傳檔案了，貼圖看下效果：

事件，屬性和方法：

SeaDragon 是個挺好玩的東西哦，看名字眼熟吧，它就是來自微軟的線上圖片服務Seadragon（http://livelabs.com/seadragon/），連名字都一摸一樣哦

其實仔細看看有點類似deepzoom，不過不是用silverlight,而是用了AJAX（感覺還是Silverlight效率高啊，其實最新的Deep Zoom Composer也已經支援匯出AJAX的圖片了，上回就說等有時間寫寫Deep Zoom Composer，看來還得下次再寫了... ）

看圖看效果：
