We've recently released SlickUpload 5.5. This was originally going to be v. 5.4.3, but it ended up getting some larger improvements, primarily around ASP.NET AJAX support. The ASP.NET AJAX support has been completely rewritten in version 5.5, with much improved support for advanced scenarios. We have also set up a comprehensive test suite to cover the ASP.NET AJAX functionality to ensure that it handles every edge case and continues to do so.
Several more things made it into this release:
- Refactoring of the FileList. The file related events and methods were removed to reduce confusion and code surface area -- you can do anything you once did with this functionality by using the identical events and methods on the FileSelector.
- Added the OnFileAdding event. This allows you to perform validation on a file before it is selected before it is added to a list. If your handler returns false, the file won't be added.
There are also a slew of small fixes and enhancements, including:
- Added support for setting progress url
- Fixed keyboard accessibility on downlevel template
