Re: Postback with no delay??

Nah, colors have no bearing on performance. It may only assist in an illusion
that there is no blinking (e.g. white page background versus a dark page
background). But that has nothing to do with performance.

Another thing, don't have images if possible. Some sites i've created have a
brand or logo and thats fine. But I stay away from using images if I can.
That is less info that has to be downloaded to the client.

Again, there are many articles on this subject. I pay attention to those
written by microsoft since they know the "under the hood" better than others
would. MSDN Magazine, and MSDN, as well as Patterns and Practices.

maybe you are right and the datagrid is causing the problem. the page I was
using to make tests just have a label and a colorfull datagrid. also maybe
using soft colors will smooth the transition between pages.

1. Avoid viewstate like the plague. Unless really necessary.
2. Use light weight objects such as the repeater instead of the datagrid
or
gridview. I guess Microsoft thinks everyone is running top of the line
machines for their servers.
3. Avoid session state all together. Session slows the performance of the
machine running the web app. Hidden fields is an alternate.
4. Enable Content Expiration for the web site.
5. Use datareader instead of dataset or other bulky objects for data
access.

There are many other performance tuning techiques available. Google
building
performance driven applications using asp.net. That should get you some
good
reading material on the subject. It really is an art itself.

Wachovia pages dont seem to use ajax since if you pay attention very
close
you will se that actually the whoole page is refreshing BUT like Firefox
or
Opera do ...not like IE. This refresh is happening VERY fast to the
eye...but is happening in the whole page. ???!!!

There are a couple of approaches if you are not running 2.0. XML-HTTP
will
get you what you want however, the page will contain a lot of
scripting.
Behaviors with the webservice htc implementation will do the trick
nicely
as well. 2.0 supports script call backs and out of band calling that
will
refresh portions of the screen. Note that these methods are still post
backs however, since the entire page does not need to be redrawn, it
doesn't *blink.

Recently I realized the Wachovia bank switched to asp.net pages. I
like
very much the way they did it and I would like to know how they
managed
to do the postbacks and the blinking between postbacks is almost
unnoticeable!

I my sites even when browsing in the local network and the pages are
very
very small I still can clearly see the blinking between pages
postbacks
(a white page in the middle)



Is there any way I can do like wachovia?



Thanks,

Alex.
