Is there anything I can do during a page postback to give any feedback to the
user of how it is progressing?
I am running some SQL queries and other processing so it can take 20 seconds
for the postback, sometimes longer and I would like to be able to show the
user something be it feedback, a progress bar etc.
I had tried launching a window from the main one right before the form
submit, which would read from a #table created in my postback, but once the
postback of the main form occurs, any refresh on the child window waits for
the parents postback to complete.
Any thoughts?
