'... is not marked as Serializable'

Hi,

Looks like the designer attempts to serialize the control object in order to
put it on the Clipboard. As your control is not marked as Serializable, this
attempt fails and the designer cannot copy your control to the clipboard.
 
From what I understand, including [Serializable] at the start of the class
definition is enough to mark the control as serializable, right? I have tried
that already but it doesn't seem to make any difference. The messagebox seems
to imply that the problem is with the UserControl class and I can't add the
attribute to that class...

I guess it is because you can't serialize a delegate\event and the user
control has some delegates\events defined in either your class or the base
implementation.
