We have fixed the issue described in this ticket and will include the fix in our next maintenance update. To apply this solution before the official update, request a hotfix by clicking the corresponding link for product versions you require.

Note: Hotfixes may be unavailable for beta versions and updates that are about to be released.

Additional information:

We have fixed the issue. Now the FileDownloading event is raised for cloud providers too. However, the InputStream and OutputStream properties of the FileManagerFileDownloadingEventArgs event arguments are not in effect for cloud providers and are always set to null.
The documentation will be updated in our next minor release.

    Hi,

    I've checked this scenario on our demo and it works fine (see the attached video). Make sure that you don't receive JavaScript errors on your side (see How to enable script debugging) and double check you code for spelling mistakes.
    If this doesn't help, send us the following information:
    - A screencast illustrating the issue on your side (for example, you can use the Jing Tool to capture it).
     - ASPxFileManager markup, which will allow us to reproduce the issue from scratch or a simple runnable project.

    Thanks,
    Artem

          Now the FileDownloading event is fired, but when canceling the download as follows:
          e.Cancel = true;
          e.ErrorText = "Você não está autorizado a baixar DocLoading.doc";
          It  throws an exception instead of showing the message.
