Hi Ng,

I'm trying to imitate the Windows Form Designer in VS. Is there a method in
the ControlPaint class to show this selection rectangle when you click on a
control to select it?Or can it be implemented on another way.

Thanks in advance and best regards
Patrick

Are you really trying to create a designer host or just move controls around
at runtime?

There is a project called SharpDevelop that explores this extensively and
it's open-source. http://www.icsharpcode.net/OpenSource/SD/

Hi Bob,

yeah, actually I'm just trying to move around controls at runtime. Do you
have any further good hints. I will browse your mentioned project.

Thanks and regards

Moving controls at runtime doesn't require IDesignerHost and all that jazz.
You can just move them around.

There isn't a method to do it directly in ControlPaint but you can use the
DrawReversible<xxx> routines to draw around where the control is on screen
to create the effect. You'll have to handle the mouse moves and such
yourself.

Hi,

ok, I'm using the mouse move etc, I can move my controls, everything works
fine. I only have two more problems:

1) how can I select a control and visualize this with this surrounding frame?
2) how can I resize my control with this surrounding frame?

it would be very nice if you have further tips. which methods of the
ControlPaint class (or another one) do I have to use for this purpose and
where do I call them.

Do you also know how to use the property grid? I've seen sth on your website.

Thank you very much in advance.

Best regards,
Patrick

Moving and sizing is pretty laborious. You need to create grab-handles that
represent the corners and the sides, track the mouse moves and button clicks
in them, redraw the rectangle and resize the control. All pretty standard
stuff but a pain to do.

Yes, I know about PropertyGrid...
