JGraph, GEF or something similar for c#

[Andi]

Hi,

I need to develop a user control which displays some rectangles and
polygons. To draw something like this seems to be easy but I need the
functionality that the user can click on some lines to select these
lines of a polygon them. Is there a framework available like eclipse
GEF or JGraph in Java.

Thanks for every hint
Andreas

Thanks for the answer. That sounds good. I have just one more problem.
I am using

e.Graphics.ScaleTransform(scaleFactor, scaleFactor);

to scale my picture. Is it possible to overgive this factor in some
way?
