    Execute function when upload is complete.

    Reply Quote
    Please forguve my ignorance.  I appreciate all your continued support!
     
    I am using, as an example, Start-uploading-manually.aspx.
     
    I am wanting to send an email when all the files are uploaded.  Where in the example code would i place this procedure, or what javascript API would i utilize, OR what ASP.net method would i use to make this happen?
     
    Looking at the example, i can't figure out where/how the control knows:  "Okay, I'm done... now do this...."

    Here's what i did to accomplish what you are talking about...
     
    dim uploadcount = 0

    Private Sub Uploader_FileUploaded(ByVal sender As Object, ByVal args As UploaderEventArgs)

    uploadcount += 1

     

     

     

    If uploadcount = 1 Then

    Email()

    End If

    'Response.Write(Uploader1.Items.Count)

    End Sub

    Problem is I don't know how many items are going to be uploaded and I need to wait until ALL the items have been uploaded BEFORE I execute the function. Is there a way to accomplish that?

    You're in luck! Thats exactly when the fileuploaded event gets fired.  After all files are uploaded.

    Then really,  the first answer wouldn't work for an action for EACH file uploaded.
     
    Any thoughts on that?

    Exactly.  From my experience, if you want to process something server-side after each upload, you must use the filevalidating event.

    My test just shows that the

    FileUploaded

    event fires after every single upload is completed. I had it send me an email with a datetime stamp and I got 3 emails.

    I should have been more clear.  The filevalidating gets fired DIRECTLY after the file has been uploaded and there are still items left in queue.  This gives you a sort-of parallel processing for the uploads.  The control continues to upload while your method is manipulating the last uploaded file. 
     
    The fileuploaded event(s) get fired after all files have been uploaded, once for each file.  I.E. When upload is complete.  So yes, it does get fired for each file, but not until all files have been uploaded.

    Hi,
     
    Because too many customers require this feature,
     
    So we have add a new event 'UploadCompleted' for it ,
     
    Please download it again and check this sample :
     
    1. <%@ Page Language="C#" %>  
    2.

    4. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">  
    5.   
    6. <script runat="server">  
    7.   
    8.     protected void Uploader1_UploadCompleted(object sender, UploaderEventArgs[] args)   
    9.     {   
    10.         string msg = "You have uploaded " + args.Length + " files";   
    11.   
    12.         foreach (UploaderEventArgs arg in args)   
    13.         {   
    14.             msg += "\r\n" + arg.FileName + "," + arg.FileSize;   
    15.         }   
    16.   
    17.         Label1.Text = msg;   
    18.     }   
    19. </script>  
    20.   
    21. <html xmlns="http://www.w3.org/1999/xhtml">

    as delamitry said, the order of the event is :
     
     
     
    client uploading file 1
     
    server FileValidating 1
     
    client uploading file 2
     
    server FileValidating 2
     
    client OnPostBack event
     
    server FileUploaded 1
    server FileUploaded 2
    server UploadCompleted([1,2])

    is there a javascript event that i can use after the progress bar disappears and before the FileUploaded method does its thing. When I am uploading several files the FileUploaded process could take a few seconds and I want to display to the enduser that processing is still going on and to hold tight.

    Terry,
     
    Neither OnUploadCompleted nor UploadCompleted are members of Uploader class. That's what it throws when I define the property of add programatically an event.
     
    Does is still work?

    Francisco,
     
    OnUploadCompleted is added recently.
     
    Can you download the latest build then try again?

    Terry,
     
    Newbie question:
     
    Not knowing how many files will be added, how do I programmatically generate an event to trigger the OnUploadCompleted event?

    Sorry for my simple generic ASP.NET programming questions but this is the last step of my evaluation to use AjaxUploader in a small installation and I'm quite eager to solve my "UploadCompleted" needs.
     
    My question is: How do I supply the "OnUploadCompleted" event handler with the correct parameters?
     
    Each added file of course triggers the "OnFileUploaded" event. But how can I, in ASP.NET, build an array of the "UploaderEventArgs", keep it in memory and, when the end user clicks a specific "Submit button", call the "OnUploadCompleted" function, supplying my array of "UploaderEventArgs"?
     
    Perhaps your previous reply somehow answers my question?
     
    Many, many thanks.
     
    Regards,
     
    Niclas
