Hi Kamen, Yes I've tried this old dirty trick but unfortunately it didn't give us the results we have hoped for. A 10 second refresh rate would have rendered the page flicker free but 10 seconds is an eternity in the life of a financial application. Once we've set the refresh rate lower (to a second which is still an unacceptable refresh time for a financial app) flickering occurred and there were just way too many requests hitting the webserver (we had about 200 test users which is a smaller subset of our expected userbase). Plus this method didn't allow to fulfill one of the requirements of the application which was to flash cells on the grid which had their values changed. Thanks for the suggestion though...

Peter, just for the sake of completeness... Have you tried embedding an IFRAME within the 'outer' page, then rendering the frame content with a separate .aspx 'for one shot only', and setting a meta refresh (of 10 seconds, or less) on the iframe? Often this works very well without flicker involved. I know it's a heresy to suggest this in the web 2.0 era but still... <sigh> it works, and is architecturally rather clean, so why not use it? -----Original Message----- From: Discussion of advanced .NET topics.

I'm looking at docs for the XMLHttpRequest object right now and it does look promising. Thanks for pointing me in the right direction. -Pete On 1/25/07, Peter Ritchie < [EMAIL PROTECTED]> wrote: > > Yes, that's wrong.
