A good form dockin component is needed

I use a free dockcontainer control in my projects. http://www.codeproject.com/KB/toolbars/VS_IDE_Dock_Container.aspx After a while I realized it has several bugs, so I should switch to a new one.

Would you be so kind to reco开发者_如何学Pythonmmend me a dock container system (like VS 2010 UI)? Does anyone know a really good, stable free component or an opensource project?

Even if the library is a little aged I was very happy with WeifenLuo DockPanel. It is well documented and really easy to use. Not so intrusive in your code - even if you have to derive from a class to became a dockable panel, you can stick your existing user controls upon a panel you will create. In plus it is reliable: I had a GUI with this in prod and I never had problem about docking even in a day by day usage.

A perfect solution for this would be AvalonDock, were it not that it's written in WPF. You can use WindowsFormsHost controls to overcome this if your requirement is using Windows Forms.
