I have a button which when clicks sends exam_id to server. The method
queries results of all the students who has appeared in this exam (No.
student > 30). I want to now print this data at client side. I am
how do I achieve this? I dont want to display this data at client
instead, I just want to show a progress bar that printing in progress
once I get all the data from server, I need to print it.
Any pointers to get started on this?
