ToolWindow and DocumentWindow both implement the same interfaces, such as IDockWindow and have a common set of properties even though their runtime behavior differs.
AllowedDockState: Specifies the allowed dock states for a DockWindow.
DockState: Specifies the current state of the DockWindow. You can set DockState to Docked, Floating, AutoHide, Hidden, TabbedDocument.
DockType: This read-only property contains one of the Telerik.WinControls.Dock.DockType enumeration members ToolWindow (for ToolWindow) or Document (for DocumentWindow).
Name: This property uniquely identifies each dock panel or tabbed document. Use this property when saving and restoring content. See Loading and Saving Layouts for more information.

Text: Specifies the text to display in the caption bar at the top of the ToolWindow and on the tab at the bottom of the ToolWindow.

DockTo(DockWindow window, DockPosition dockPosition): Docks a window with another window in the same container. The example below docks "Bottom Window" to the container of "Top Window".
