    UploadCompleted firing before all files are uploaded

    HI,
          The UploadCompleted appers to be firing before all files have completed uploading.
         I have the UploadAttachments  in an update panel say UP1  and another update panel say UP2 with dropdowns, textboxes etc some of which cause a postback.  Both UP1 and UP2 are set to conditional.
           A postback in UP2 is causing the UploadCompleted to fire if at least one file has been uploaded even though the upload is in progress.
     
    Part of my code is pasted below.
    If while the upload is going on (and after at least one file has been uplaoded)- you click the button which says Click Me - the control will jump to UploadCompleted and set the hidden variable to C.
     
    Can you please tell me what I am doing wrong? I am trying to have the file upload go on in an update panel while the user continues to fill in data in the second update panel. And I need to capture which completed first so I do need the UploadComplete to file ONLY after the file uploads are all completed.
     
    Can you provide me an alternate solution?

    Hi - any update on this.
    Were you able to reproduce this error with the sample I posted?
    Thanks!

    Re: UploadCompleted firing before all files are uploaded

    Please check this example. When you click the post back, the form is post backed. However the file upload progress will only start when you click the submit button.

    Re: UploadCompleted firing before all files are uploaded

    HI,
     You did not read the sample. I am already using the manual mode. I want the file upload to start and at the same time allow users to  enter data.
    Please try the sample I sent and let me know if what I'm doing is possible or not.

    Re: UploadCompleted firing before all files are uploaded

    Hi,
            It seems to be that your UploadCompleted event is firing on the 1st postback event on  the page instead of on the actual file Upload completetion.
    Please let me know if this is true.  Do you plan on fixing this or is there is a workaround?
     
    Thanks,
