before the dialog box could appear. Is it possible to show any loading image or any status before the dialog box appears to indicate the end users that exporting process is running in background. Currently, there is no such indication and end users are not happy as it is looking like unresponsive report.
This is a very good question. I like the idea of progress bars or some sort of message prior to lengthy functions. Though I don't have an answer for you right now, I will do some research and reply back when I can.
I just wanted to let you know this question will not go unanswered.
