这次更新主要是两个新控制元件Seadragon和AsyncFileUpload与Bug修正 The Seadragon control enables you to pan, zoom, and make an image full screen. The control performs all of these fancy image effects using pure JavaScript and it works with any modern web browser. Seadragon控制元件是一个能够对图片做一些特效，如利用滑鼠摇摄图片、放大缩小和图 片全萤幕。这个元件使用纯javascript，能够运行在目前各大浏览器。 You can try out Seadragon by visiting the following web page. Click on the image of the bicycle that appears half-way down the page. http://livelabs.com/seadragon-ajax/ Now with this release of Ajax Control Toolkit, including and controlling Deep Zoom from an ASP.NET page is also very easy: <ajaxToolkit:Seadragon ID="Seadragon" CssClass="seadragon" runat="server" SourceUrl="sample.xml"/> James Senior just released a screencast on how to create Deep Zoom contents for the new Seadragon control: http://channel9.msdn.com/posts/jsenior/ Seadragon-Ajax-Control-Quick-Start-Guide/ AsyncFileUpload: This is by far one of the most requested controls for ACT. File upload fields, while a part of HTML, do not work with Ajax/XHR requests (for security reasons, JavaScript can’t access the contents of the field). The only way to use them is to get the browser to do a real form post. AsyncFileUpload控制元件，这是最被期待的控制元件之一，在以往档案上传元件无法使 用在ASP.NET AJAX扩充原件上面，只能用form post方式达成(基於一些安全性因素)， 使用方法就类似一般FileUpload操作方式。 This new control makes it a lot easier to handle file uploads from your Ajax applications by providing an abstraction on top of the form posting: <ajaxToolkit:AsyncFileUpload OnClientUploadError="uploadError" OnClientUploadComplete="uploadComplete" runat="server" ID="AsyncFileUpload1" Width="400px" UploaderStyle="Modern" UploadingBackColor="#CCFFFF" ThrobberID="myThrobber"/> It works pretty much as advertised: just drop the control on the page, and you can upload files without a full postback. It looks just like Ajax and requires no plug-in of any kind.AsyncFileUpload The control has client and server-side events that get triggered when the file has been uploaded. On the server-side, you have access to the uploaded file’s byte stream, which you can save to disk (or database, or whatever). Bug fixes: This release also has some new bug fixes (courtesy of Obout) for some of the top-voted issues.
