.NET Windows Forms in a Nutshell

Name

ContainerControl

Synopsis

This control extends ScrollableControl and also implements the IContainerControl interface. It provides the base functionality required to manage the focus control and tab ordering for the controls that it hosts. It also adds support for a ParentForm member, which provides the root containing form for the control, and the ActiveControl (implementing the IContainerControl interface), which determines which of the hosted controls has the focus.

Note that the ContainerControl never takes the focus itself. It always passes it through to one of the contained controls.

You would not normally derive your own containers from this class. Instead, you should look at UserControl or Form.
