Greetings. I was curious to know if there is a way for the AJAX client to show an "hourglass" or similar icon that will let the user know the data is loading.
I have a fairly big pivot table with calculated expressions in it, and it takes a fairly long time to load. While it is loading, there is currently no way for a user to know what is going on in the background. A simple notification that there is something happening in the background would be desirable.
