How to know how control is placed on a form

[Andrea Moro]

Control may be added on a form by double-clicking
it on the toolbox, or selecting it and then drawing on
the form.

Is there a parameter, a variable, a message that let
me say how control has been painter - before the
oncreatecontrol method?

Hi,

The control has a parent changed event. Maybe that is what you are
looking for.

it isn't what I'm looking for. I see for this property before
post, but there is any returned parameter, or casting option
that let me know in which way control is placed (designed
or dragged/double clicked).

I'm curious: why do you need to know?

Well Jeff,

maybe that I'm missing something that may be solved
in another way, but actually I don't think to anything
else.

I would like to setup a defaultsize to the control when
it's posizioned by dragging or by double cliccking on the
toolbox.

I hoped that defaultsize property might be usefull, but
it's is readonly and not overridable. So I cannot set a minimu
control size and value proposed by framework is too much wide.

Isn't there any other way to set up it?

toolbox.

One way is to use your own designer, which inherits from the control's
original designer. In it, you would place something like this:

Public Overloads Overrides Sub OnSetComponentDefaults()
MyBase.OnSetComponentDefaults()
MyBase.Control.Size = New Size(496, 312) ' whatever your desired
default size is
End Sub

Andy thanks.
I don't tried it, but it sounds like what I'm looking for.
I searched for it a lot of time, but one of the main problem
of the ide - IMHO - is that doesn't show all possible
overloadable subs/functions.
This mean a lot of wasted time to search possibile routine
that can help us.

I think that MS - in the next version of Ide - should add
all overiddable routine inherited from all classes from
within a class depends.

I'm not able to overloads the OnSetComponentDefaults.
Framework is saying that those method isn't a part of the
base class.

I'm inheriting from usercontrol.

I taked a look to the object browser, and serching for it,
it doesn't display anything. If I setup a reference for system.design
assembly for the working project, I can see it, but always I
don't know how to use it.

Can you help me again?

I'm doing a lot of confuision with assembly, namespaces etc.

System.ComponentModel.Design > ComponentDesigner Class
seems doesn't exist on my pc.

Your control will need to use its own designer, and that designer class is
where OnSetComponentDefaults goes. Check out
System.ComponentModel.DesignerAttribute in the help.
