What control is used in Visual Studio ToolBox panel?

Please, read the header. Nee开发者_如何转开发d to do the same. What is that? TreeView, ListView, ToolboxContainer?

In fact it's called ToolBoxPane class and it's located and docked inside GenericPane class.

Are they the specific MS VS controls?

Infragistics calls it an ExplorerBar, but if you click on the video there are different looks available. One of which matches the Toolbox.

Telerik has a Treeview, which can certainly be customized to replicate the look of the Toolbox.

DevExpress has a NavBar, which again can replicate that look.

I'm sure there are more, but that's a cursory search for WinForms controls (which I'm assuming is what you want, based on your screen shot).
