Disabling ToolBoxItem in Vs ToolBox after some scanrio

sarahh

1/17/2012 8:15:00 AM

Hi,
I make a designer with Visual Studio 2010 and use also the Vs
ToolBox(adding custom controls) by the following:

IToolboxService toolBoxService =
(IToolboxService)Package.GetGlobalService(typeof(IToolboxService));
toolBoxService .AddToolboxItem(toolboxitem, category);
toolBoxService .Refresh();

After dropping specific toolboxitem control on the designer I need
that this item will be disabled (grayed out).

I have the following questions:
1. How could I disable toolboxitem, whereas other toolboxitem in it's
category remain enabled?
2. How I disable the dropping of this toolboxitem?

Thanks.

Of course, we all learn through intelligent discourse,
but it's not particularly productive, educationally or
professionally, to be sloppy because you _expect_ others
to clean up after you.

'If I'm wrong people will correct me' is an attitude
that invariably places a burden on others to actually
do so. At the very least it is taking people for granted.

Asking questions is more conducive to development
than giving careless answers, whether qualified as
recollections or not.

Not in general.

In general, I might agree, but as it was already pointed out, Tim
went out of his way to highlight that his memory might be unreliable
in this matter.

If the only people giving answers are the ones who are totally certain
that they're right, we'll get a lot of very poor answers.

I still seems odd to give advice to newbies that is actually wrong. I
sometimes post stuff I don't know to be correct just so I can test the
waters. But if it went to a newbie I'd try to label it as tentative.
In front of experts I'd just say it.

for someone who doesn't understand status you don't half go on about
it...

never bothered me very much. Similarly I don't take the mick out of
people who don't know things I do (we're all ignorant about
something). The people who bug me are what I call the willfully
ignorant. It's not that they don't know something but that they don't
know something and pretend they do and won't be corrected.

I can model it well enough to explain it and describe its effects, I just
don't have the experience. I dislike people who insist that I'm actually
motivated by something I don't experience. (It's IMPORTANT. Someone
is WRONG on the INTERNET.)

Yeah. That can be either fascinating, horrifying, or funny, but is also
nearly always annoying. (I've been watching a particularly beautiful
case of it descend into madness, as someone who guessed wrong on a
physics brainteaser has spent months defending an ever stupider position,
and is now at a point where, to preserve his ego, he has to deny pretty
much the last four hundred years of basic physics. It's maddening,
and yet, strangely awe-inspiring to watch.)

Okay, thanks to everyone. I think I can see where I was going wrong
now!
