Share a callback based on the No Refresh Upload progress bar control of the source code. This control uses a httpmoudule based on the gem's Upload progress bar sample, which is encapsulated as a control for ease of use. Without any code, simply set web.config, add a HttpModule reference, and then drag the control onto the page. The file save operation on the page is exactly the same as the traditional asp.net file upload. You can set the property upload process error or upload success when you jump to other pages. Compatible with Ie,firefox,opera. Other environments are not tested, but because they are based on asp.net2.0 callback, other browsers should support XMLHTTP or IFRAME as long as they support it.

(in the native run example note that the program's directory is set to write to the web account, otherwise the upload file will be insufficient permissions error)
Here's a short list of web.config and Default.aspx and Default.aspx.cs in the example.
