Hi Georgi,

Has this issue been resolved yet? I am running into the same issue with needing to access the HttpContext.Current.Session as well.

They were able to duplicate this issue, that's why they opened the support ticket.  I assume they will post on this thread when the fix is available.

My workaround is to let the upload save the file in the upload directory and I rename it in the server-side uploadfinished event, then on the clientside onuploadFinished event, I perform a click event on a hidden button to initiate postback that will process the file.  Since I'm renaming the file to ensure that it is unique, I create a cookie (suggested by support) with the file name to attach to the response.  This cookie is then available on the postback and that's how I know what file to use.  This works for now, but I am very disappointed in the implementation.

This is what I would hope for:

1) The upload control is configurable for one single directory to receive uploads.  It should at least allow you to change the directory per control.

2) I'd actually prefer it didn't write my file to a directory, I wish I could handle the upload event and just get the bytes that were uploaded so that I could just take the file in memory and process it as I desire.

3) Once the bug is fixed and I have access to the session and I can process the file on the upload event handler, it would be nice to be able to return a serializable object in a JSON format back to the client so that I can provide information back to my user.  Because even if I can process the file as soon as it uploads, the way it is designed, it seems I'm always forced to make another request to get the messages that are needed to display the results of the operation.

Hey chadc,

I can propose you workaround to use session in server side events you can just set in Page_Load var session = this.Page.Session. Please try this. Here are my comments for your proposals.

1) The main idea for upload directory is to have only ONE temporary folder where files are saved and then using server side events to save them anywhere you want or to do with the files what you want. But we have discussed this and we think to implement each control to be configurable to have separate folder. I hope we will implement this for the next Service Release.

2) We plan to implement saving files in memory stream(or byte array) for the next SR.

3) As I said one workaround is to play with your session in page_load. For instance to set var session = this.Page.Session in your Page_Load event handler.

Thanks,

This fix does not work for me.  With out the line of code suggested, I get an error thrown(which is expected from what this post states).  With the fix in place, I get a blank value.  (I am coding in VB)

I have added this to the page_load

Dim Session = Me.Page.Session

Please let me know if there is something I am missing on the work around.

We are using 

string sessionValue = Session["SomeData"].ToString();

this works fine for us.

FYI: The page_load event never fires during any webuploader event handlers.

This is what I get.

Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the <configuration>\<system.web>\<httpModules> section in the application configuration.

I have no problem with Sessioin variables in other parts of the page, only in the webupload uploadfinishing call.

Thanks for your help.

Hi, I still have the error when using the upload component in a StateServer environment. It doesn't happen when using InProc SessionState. Any solution ?

Hi,

This sample will work for all the three released versions - 11.1, 11.2 and 12.1

Thanks,
Miro Hristov

This is for version 11.1, not 12.1

Hi,

Please check the attached sample. I have added a simple webpage where I use session to store how many times files are uploaded.

DGilbert17, please can you send us full sample? You can send us in VB or C# as you prefer

Thanks,

Miro Hristov
