I have a server code task which runs during a progress bar display (startTask). In the server side OnRunTask handler I save an object in session. Then in the ClientSideOnTaskDone client handler I update a callbackpanel (in a master page). In the Callbackpanel's OnExecute server handler, I try to get the object from the session but it's null?
What's the best way to pass an object in the workflow I described?
I saw a post about saving the session in a file as in: e.UpdateProgress(100, "../temp/" + session_file);
Is this the only way to pass the object? It seems I have to serialize the object in the file and then deserialize it upon reading. I prefer not to deal with files.
I am thinking of not using the runTask. i don't need to send updates to the progress bar. Just to close it when server code is done.

Hi,
You can try to use setTimeout to delay your callback and see if it works. Using a separate file obviously will work, but then you will have to delete it.
Thanks

Thanks. I had a sleep of 3 seconds while I was testing so it doesn't seem to be a delay issue.
I ended up serializing the object to XML, sending it to the client which sent it to the callbackpanel which deserialized it.

I do not know why the session variable is not saved. However I am glad to hear that you found a solution.
