Hi Support team :-)

I have a slight issue where the postback finishing before the actual server task is complete. Currently I am not able to make any changes to the page once the task is complete. The task is building a DataTable and then converting it to XML and storing to a file in the location of the application on the server. I tried setting the URL of the file to links that are placed on the page. I have also tried to transmit the file but I am receiving a "headers are already sent" error which signifies that the postback completes before the server task is completed.

I am using AJAX with update panels and progress panels associated with the update panels.

I am updating the progress bar from server side while the task is running.

Please let me know how I can update controls on the page once the task is complete.

Any help would be greatly appreciated!
Thanks!
