These classes are not marked as sealed (C#'s equivalent to final), and can be derived from. But they do not support visual inheritance.
You can only use visual inheritance on Forms and UserControls. This should come as no great surprise because these are the only kinds of control you can edit visually anyway. So in other words, the Forms Designer supports the exact same range of types for Visual Inheritance as it does for normal editing. If you want to make controls that derive from controls which are not Form or UserControl based, you just have to do it in code. The simplest starting point is to create a new Custom Control class and then in the source code it produces, change the base class to be whatever you wish to derive from. -- Ian Griffiths DevelopMentor ----- Original Message ----- From: "Reggie Burnett" <[EMAIL PROTECTED]> > Can objects like Panel be visually inherited with designer support?

Are these all marked final or something? You can read messages from the DOTNET archive, unsubscribe from DOTNET, or subscribe to other DevelopMentor lists at http://discuss.develop.com.
