A couple of questions about FileDownloadWrapper:Is there any

A few questions about FileDownloadWrapper:

  • Is there any way to have a dialog window with a progress bar that appears in case creating the file to download in takes some time to generate?
  • Is there any ability to add any validation checks before firing the download on the button?
  • Is there a way to programmatically click the button? I ask because I tried to create it as a hidden button which would be clicked by my primary button (with validation, etc.) however it only works if the the FileDownloadWrapper is visible.

No to all three.
