Creating custom controls

Question

I want to create a custom control where the footprint of the control is a small button, but when clicked it pops out to larger area. An example would be a combo box. On the form it only takes up the space of one line, but when clicked it pops down to offer selections. When creating composite controls, one has to create the control at the size it is on the form. In the end I would like to have a small button sized control in my toolbox which I can drag onto a form, when clicked it would display a larger area with custom stuff in that area.

Answer 1

But a combo box, when expanded, doesn't cause other controls to move around or cause the form to change the layout.  It just creates a window on top.

You can use a borderless popup form to do this.
