Ajax Uploader - Uploader_FileUploaded server event not firing

    Ajax Uploader - Uploader_FileUploaded server event not firing

    Reply Quote
    Hello,
     
    I am using an ajax uploader control and setting the manual start upload to true.  My exact code is below.  When I use this code on a page that does not have any Jquery ajax calls everything works fine and the file that I select for upload gets uploaded to my C drive when my submit button is clicked.  If I use the same code within a page that makes Jquery ajax calls, the 
    Uploader_FileUploaded event is never hit, the progress bar turns green and it looks like it uploads the file that I selected for upload when the submit button is clicked but the file does not end up in my C drive.  It is probably being uploaded to some default temporary location which I don't know or it is not actually getting uploaded.  Any reason why the 
    Uploader_FileUploaded event would not get fired on a page that uses Jquery Ajax and would get fired on a page that does not have any Jquery ajax calls? Also, by default where does the Ajax uploader control upload files if I don't specify a different directory in the 
    Uploader_FileUploaded event?
     
     
    Thank you.
