UserControl inheritance

[Stefan Hoffmann]

hi @all,

I have a lot of similar looking pages (TabPage) with a lot of code
behind. I want to extract these page contents to user controls. Because
they have all the same basic layout and some code in common, I like to
have this inheritance chain:

public class AbstractContent : System.Windows.Forms.UserControl {}
public class ConcreteContent : AbstractContent {}

I have placed a SplitContainer on my AbstractContent. Now I want do
derive ConcreteContent from it, so that I can add controls to the
inherited SplitContainer.

This does not work:

My goal is, that I can use the designer "as usual" for editing my
ConcretePage.

How can I do that?

If it's not that clear:
I can add controls to the UserControl area, but not to the derived
SplitContainer, cause it's locked.

How can I unlock the SplitContainer?
