How to add a dockable window in visual studio 2008

Question

I want to add one of those dockable windows panes, such as the solution explorer in visual studio 2008 to my project, are they in fact called dockable tool, or shims? And where do I find it because obviously its not in the default list?

Answer 1

There is no built-in control in .Net that does this; you need a third-party docking suite.

Commercial ones include DevExpress XtraBars.
Free ones include DockPanel Suite.

Answer 2

I use the DockManager from Infragistics NetAdvantage for this.
