Page Truncation

[randy.buchholz]

I have been encountering strange behaviour on client machines where the
pages truncate the display in the middle of the page.
At some point the browser just goes white from one line to the bottom of the
browser.
No error shows, and the visible portions of the pages function normally. I
can't find any way to reproduce. It will happen on different pages and will
truncate at different points on the same page for different users and
sessions. This happens across the entire width of the page crossing
masterpages and content areas I am working in VS2008 and running both
IIS5.1 and 6.0 (different boxes). Any ideas?

Are u able to reproduce the same problem across different computers on
different networks. If you are able to do so, then the problem might be
closer to the server.

or else you may want to check the network settings. I had issues with a
particular set of users not being able to Postback to the server and the
viewstate gets truncated. never had problems with the get though.

have you tried lookinga the view source. Do you see anything specific.

I haven't been able to reproduce the problem, but it happens on more than
one machine. All of the machines are inside the firewall and use a common
config. It started with one machine about a month ago and was inconsistent.
You could go to a page one time and it would load fine. When you returned
to the page later it would cut off at the bottom. Later in the session it
may work or may not, and might "spread" to other pages that were working
correctly. Really inconsistent. It went away by itself and I assumed it
was the IE browser config on that machine - It worked fine on non-IE
browsers running in parallel.

I hadn't seen it for a while and yesterday while giving a demo (to upper
management of course) it started again on a different machine. View source
shows the same for working and not working instances. I added a button with
a key mapping to several pages and even when the button doesn't render on
the screen I can still activate it from the keyboard. It just looks like a
white panel is overlaying some of the screen image. I have even seen this
on simple read-only pages with just a sql data source and gridview - no
code, panels, or anything else.

Even stranger is that I have other applications running on the server that
don't exhibit this behaviour. I tried cloning all the config files and
settings from an app that has been running fine for over a year and no luck.
At this point I am just baffled and not sure where to look next and willing
to try any approach to try to resolve this.

Thanks

Randy,
If you would like to go over the Request / Response headers directly you can
use WFetch as explained in the article below. If you google you will be able
to read more about it.
http://support.microsoft.com/kb/284285

Since you are able to reproduce the same issue, but works most times, I
would assume that there is something wrong with the way the HTML is
generated and interpreted by Internet Explorer during those times. You
mentioned that during these times,the page worked fine on other browsers. I
do not think this is a server side issue, but purely related to Internet
Explorer.

I would ask you to post the resulting HTML (by using the View Source option
in IE) during this abnormality, but since you might have security
considerations doing that you may email me directly with the HTML if you
like and I will have a look. My email address is trevornews at gmail dot
com.

Additionally you can use the View Source option and save the resulting Text
information into a file with a .HTML or .HTM extension. Open this file and
see if are able to view the page correctly in Internet Explorer and other
browsers. If the page loads normally, then it could be related to running
the page only in IE (realtime).

If it happens only in IE realtime, I would check to see if there are any
browser add-ons and disable everything. You may want to make a note of which
ones were enabled (maybe take a screen shot and save it some place) and
disable all add-ons and then try to reproduce this problem
