Hi Alfons,
Thanks for posting in the community! My name is Steven, and I'll be
assisting you on this issue.
From your description, when you loaded a page again(second time) using
"window.showModalDialog" javascript code, the page(be opened) seemed not be
newly loaded(page's server Load event was not fired)
However, when you change the IE's page "check for new version always" as
true, it worked, yes?
If there is anything I misunderstood, please feel free to let me know.
I've done some tests on my side and did encountered the same problem. I've
also tried Steve's suggestion that set the page's client cache attribute
via:
Response.Expires = 0;
Response.Cache.SetNoStore();
Response.AppendHeader("Pragma", "no-cache");
Yes, this did work. So the problem is due to the client cache. The page
popuped be the "showModalDialog" may be cached by default. You may also try
Steve's solution to see whether it works for you.
In addition, here is the test page I used to test Steve' suggestion, you
may have a look as reference if you have anything unclear:
