    Hi All,

    I  have an .aspx webpage  in my .Net 1.1 application.
    It contains a .ascx web user control with a radUpload control and radpProgressManager and radProgressArea.
    when I clicked Save button in .aspx page I have got an error
    "r.a.d.upload Ajax Callback Error. Source url returned error: 12031. undefined"
    The file upload works fine.

    or is this error related with internet connection problem?

    Please help.

    Thanks

    Neeraj-

    Not sure if you're still dealing with this issue, but I'd suggest re-asking the question in the RadUpload (non-ASP.NET AJAX) forum:


    You'll probably get the best attention to this issue there. I can't provide much input since this is a very old version of RadUpload, but hopefully the upload support guys can give you a hand.
