How to stop Buttons from moving in inherited form?

Question

Hi,

I am experiencing a strange issue and i'm out of ideas on how to fix.

I have a couple of base forms (in seperate UserControl DLL) which are inherited by the forms in my application. One of them is for example "FormEditBase" which contains standard buttons like add, update, delete, close

In my inherited forms however, these buttons move their location ( even outside of the visible form)

I've tried just about everything i could find:

lock them redraw them from scratch redraw just the buttons change the modifier access from public to protected internal

So my question is actually in 2 parts:

1: should i make a "OnSave" abstract void to handle this and keep the buttons internal ? 2: Is there a way so design time movement of the buttons does not occur anymore ?

Any ideas are welcome.
