What is maximum number of controls allowed on .Net
Windows Form?

I know it's 254 in VB6.
 
Why, are you coming close to the limit or just curios ?? :-
)

But you aren't the first person to think of this question
apparently. Some responses I found were one guy who added
512 buttons without any problems and another guy thought
the only limit now is on system resources.

Well, I just added 1080 buttons to my form (curiosity got
to me) and it took about 65 seconds to load in debug
mode. Granted I don't have a P4 3Ghz system here but I
wouldn't suggest it in an application :-)

I am of the oppinion that system resources will become the
issue before any limit (if one exists) will.

AFAIK there is no hard limitation. Nevertheless, I would not load more than
256 controls onto a form because the form will require a lot of memory.
 
Hi Hal,
We had a test with dynamicly removing controls some weeks ago.

Therefore Nak has made a test program, that with a randomizer puts about
5000 buttons and 5000 labels on a form.

I do'nt know which persons have used it to do the test, but I did not see
here any complains about that program.

I added something to make the amount of controls endless and I have stopped
that at 25000 (in debugger mode).

It took to much time to make this as normal behaviour.

ps. Maybe Nak has the program still downloadable.
