Yes, that's called autosizing. You can use the LCL properties or you
can use OnResize.
For the Height of the Form itself you can use OnCreate or OnShow.

Height is stored by the LCL. You can not set stored = false (unless
you change the LCL source code).

Can you give some more details, what you want to do?

AdjustClientRect work the same under designtime and runtime. Under
designtime you can drag the controls to some invalid positions, same as
at runtime. The only difference is that at runtime the autosizing is
done immediately, so you can not see the invalid positions. Same for
Anchors.
