    Hello Telerik support. I'm not sure if this is a known issue, but I just ran into something weird and I wanted to ask about it. I have a set of test upload files that I made, Test1.txt, Test2.txt, etc, and when I try to upload it with the ASyncUpload control the file progress bar stays yellow and the upload never completes. The files have nothing inside of them, and are just new files typed as a .txt file. I've tested it on IE 8 and Firefox 4 and they both never complete the upload or display any errors. However, when I added some text inside of the test files the uploads completed correctly. Strangely enough, when I tested the files on the Telerik demo pages for AsyncUpload they did complete the upload. This shouldn't be a problem unless users try and upload blank files accidentally, but I would like some way to detect this condition and display an appropriate error message and kill the upload if it happens.

    Hello Ryan,

    I confirm the problem. The good news are that we already fixed it for the latest service pack and now it is possible to upload 0 byte files. I suggest that you upgrade.

    Hi Zin,

    Last year we introduced a new upload module and I am afraid the same issue appears again. We are aware of it and the problem will be resolved as soon as we could.

    Is there a temporary solution to fix it?

    Hello Zin,

    Unfortunately it is not possible to create a workaround as a temporary solution. The issue is resolved and next week the fix will be available in our internal build.

    Kind regards,

    Hi Zin,

    I just tested our online demos and it is possible to upload files with zero byte size. Could you try them at your side and let me know the result?
