I want to use a collection of controls in a usercontrol. It should work like
the built-in toolbar, that means i want to add and remove buttons with the
designer.
my problem is that the designer does not save settings within my
collection - the entries stay in the generated code but when i run the
project or reload the source my property shows up empty.
I also noticed that I would need a 'add' the individual buttons to the
collection in the generated code but i have no idea how to manage this.

Why doesn't the designer store my collection and how do I inject custom code
when editing my collection?

Thanks,
