If you have used docking Windows in previous versions of .NET, the DockPanel is used to provide that functionality in WPF and Silverlight. The DockPanel is not a part of Silverlight 2. It is a part of Silverlight Toolkit but I am sure it will be a part of the next version of Silverlight.
The DockPanel control is a layout control that acts as a container for child controls. The DockPanel allows child controls to dock in left, right, top, or bottom sides of the panel.
