What is KUpload+ AJAX Progress Bar?

KUpload+ has a special add-on control, called KFileUploadPlusProgressBar, which includes Ajax based ProgressBar. It displays various status information about the current upload, just like pure HTML progress bar but instead of popup window it uses an inline progress bar with the AJAX technology. KFileUploadPlusProgressBar Control takes full advantage of AJAX and the new features of Microsoft's next-generation IDE - Visual Studio .NET 2005, hence allowing developers to enjoy significant productivity gains, while delivering feature-rich, standards-compliant and cross-browser compatible web applications.

Can I customize the Progress Area & how?

Yes. The AJAX Progress Area is fully customizable. The progress area displays various information about the status of the upload progress. Each of the progress area elements can be easily hidden or shown using its corresponding property:

  • ShowTotalProgressBar for the uploaded bytes progress bar (the topmost progress bar on the screenshot).

  • ShowTotalProgressData for the text representation of the progress bar above.

  • ShowCurrentFileName to show/hide the name of the currently uploaded file.

  • ShowTimerData for the estimated and the elapsed time of the current upload.

  • ShowCancelButton to show/hide the Cancel button which can be used to notify the application that the user wants to cancel the current upload. The actual postback cannot be cancelled via javascript, so the user must wait until all form data is sent to the server. Then the developer can check the IsUploadComplete property of ProgressBar object for the status of the Cancel button.

I am evaluating AJAX Progress Bar. When I upload a file, I only get the spinning icon during the upload. Why I do not get the TotalProgressBar, the CurrentFileName, etc.?

To resolve this problem:

  • Make sure all the directories i.e. skin, resources, etc. exists in same way as shown in demo project.

  • Make sure required files exist in this directory.

  • Check web.config file and compare it with web.config file of demo project.

I am evaluating KUpload+ AJAX Progress Bar. I found that adding the KUpload+ HTTPModule in the Web.Config breaks any other regular file upload input box (non-KUpload) on the site. Why?
Since KUpload+ is a HttpModule, it processes all the request and collects data. You can turn-off this behaviour by passing querystring in your request. Use querystring kuploadplus=0 to turn-off KUpload+. By default KUpload+ is On. Please note that this functionality is available in KUpload+ 2.0 and upward versions.

How can I get the AJAX Progress Bar to show when I click the form submit button instead of putting the script in the HTML form tag?
You can get this by using visible property of AJAX Progress bar. Initially make AJAX Progress invisible by setting visible property to false. You can make AJAX Progress bar visible through the Java Script. For more details refer Demo project files.
