Create custom winforms container

Question

I want to create a control in winforms with same behavior as the container controls. I mean: in design mode, when I drop controls in it, it will group then, just like a groupbox

Answer 1

Maybe this is what you need, I found it at CodeProject a time ago:

Designing Nested Controls:

This article demonstrates how to allow a Control, which is a child of another Control to accept having controls dropped onto it at design time. It is not a large article, there is not much by way of code, and this may not be either the 'official' or best way to do this. It does, however, work, and is stable as far as I have been able to test it.
