No Flicker Firefox
It is interesting that in doing the first Ajax exercise, there was no flicker in Mozilla Firefox 3.5.5 even before entering the Ajax code. Before and after were identical. Flicker in the before code was quite apparant in the latest MS IE

Hi there,
Yes, the problem is not always easy to see at first, especially not on a local machine. However, it becomes more apparent when your pages grow in size, or when you're using a remote server.
Cheers,
Imar

I have found that flicker-free change over between pages generally is a problem with IE - I believe it's inherent with IE - but not most other browsers. It became annoying for one of my sites when I went for a dark background. Following a tip I spotted in another forum, I dropped the following in the head:
Code:
<meta http-equiv="Page-Enter" content="progid:DXImageTransform.Microsoft.Fade(Duration=0.1)" />
<meta http-equiv="Page-Exit" content="progid:DXImageTransform.Microsoft.Fade(Duration=0.1)" />
and the problem has gone.

It all depends on the site, its content, its design, the browser, the performance of your PC, the bandwidth on your network and more.
AJAX and technologies like the UpdatePanel are designed for other purposes than the progid filters for IE. The latter enable you to maintain the old page in the browser until the new one has fully loaded. UpdatePanels on the other hand are designed to update only part of the page without affecting the rest. This is often used to avoid page flicker, but can also be used for other scenarios (continuously refreshing some content from the database for example).
So, IMO, there is a lot of room for the UpdatePanel, even if other browsers suffer less from page flicker....
Cheers,
Imar
