Hi,
I have tested it all the ways you recommended, but with no luck. Here is the way I'm doing it at the moment. Please note that the start and end time for the processing is only where I add the data to the series and not the page load time.
Create a "Temp" directory in the web application project for the *.tee file.
Note: I use the endRequest method to load my tee file after a asynchronous postback from my button.
