RadAsyncUpload Not allowing all files to be uploaded

[Joshua Swain]

I have a problem using the RadAsyncUpload control.  I have not been able to figure out how to allow the control to upload all files (ie., All Files (*.*)).  If I set anything in the "AllowedFileExtensions" property, or use any filters, then it only allows those files, which is to be expected, but setting a wildcard value in either one blocks all files.  If I leave those items unset then only certain files (mainly text files) are the only files that don't get block.

So my question is how do I set up the control so that I can upload any file?

Thanks for the help,
Josh

Edit: Well, I am sorry to waste anyone's time.  My problem was apparently a file size issue, not a extension filter issue.  Once I had that problem fixed, all files uploaded no problem when I left the "AllowedFileExtensions" blank, and added no filters.
