I have decided to make some changes in source code of ajaxFileUpload but i don know after making changes how can I use that.
How to build that and add the newly modified file to ajax library.
I have googled about this but dint get any solution.
I need help regarding this.
You can make the change in the .js file but make sure to recomplie and add the newly compiled .dll to your project. I think if you found a problem with browsers and know the problem, I'd suggest submitting the fix on Code Plex so it can be included for everyone vs. creating your own version. This way when a new version comes out you don't have to refix the problem before adding the new features.
