Is there a limit as to how big an aspx page's html can be? (number of
characters)

Why do I ask? I have a webform with a lot of ActiveX controls (shows up as
OBJECT in html). When I place like 35 of these objects the form shows up
BLANK in a web browser. When I remove a few (ANY few) I can see the page.
Any ideas?

Thanks.
 
That's the interesting thing. It has some scripting stuff at the beginning
but NOTHING IN THE BODY. See below...

theform = document.Form1;
}
theform.__EVENTTARGET.value = eventTarget.split("$").join(":");
theform.__EVENTARGUMENT.value = eventArgument;
theform.submit();
}
// -->
</script>

Ok, how about replacing one of the <object /> elements with the same number
of characters in a <div> or something. That will tell you whether it's a
question of the size of HTML or the number of ActiveX controls.

TEST 1: There are like 35 OBJECT tags. I kept removing them until the form
showed up (at 25 OBJECTS). I added a bunch of 'aaaaaaa' until I was over
660,000 characters. The form was blank at first but after about a minute
somehow the form refreshed and everything appeared.

TEST2: I created a brand new web form and added the same 36 (activeX)
OBJECTS the it. Ran the webform - IT WORKED! Went to HTML view and played
the form, it did NOT work (same results). Any ideas?

FYI:

It shows up FINE in the Design View. Also, I copied/pasted the text in
Word
and it came out to 616,242 char (w/spaces) and 526,708 (without).

Please assist. Thanks!

Also weird, when the form shows up blank I hit refresh twice and it shows me
this:

I recommend you wait a while. It could be taking IE a while to parse all
that text. Load the page, then don't touch IE for a minute or two.

What do you mean "Went to HTML view and played the form"?
 
I did wait a while and the page fully loaded. I looked at the source to
verify.

I "Went to HTML view" in the Designer then went to Debug/Start. It worked
when I viewed it in Design view, but when I switched it to HTML view then
clicked on Debug/Start it failed to load (it was blank).

This is the part that doesn't make any sense. Did you also save the page
after switching to HTML view?

Are there any squiggly red lines in HTML view? Any complaints when you
format the HTML?
 
I did another test.

Here's exactly what I did:
1. Create a brand new ASP.NET project with a webform1.aspx.
2. Placed 50 occurances of the non-managed ActiveX control on the
webform1.aspx. Saved it.
3. Debug/Start. Everything shows up fine.
4. Hit 'Refresh' everything is blank. (Even if I wait a while.)
Debug/Start again - still blank. The View Source is this...

If you want I can send you the ActiveX control for you to test.

Thanks!

This is looking more and more like an IE bug (or rather, an MSHTML bug).
Recall that both IE and the VS.NET design mode use the same HTML rendering
engine.

I'm about out of clues. I'm guessing that some piece of code doesn't like to
see such an unusually large number of ActiveX controls. Perhaps you could
create a few meta-controls? Five controls each performing the functions of
ten of the originals might work better.

Also, have you played with the security settings? Try using the least-secure
settings and see if it's any different.
