AllowedDockStates

Updated on Nov 3, 2026

AllowedDockState property gives you the ability to determine the available dock states per ToolWindow. There are several options for this properties which can be combined by bitwise operations. For example:

Allow two states only.

C#

toolWindow1.AllowedDockState = AllowedDockState.Docked | AllowedDockState.Floating;

VB.NET

toolWindow1.AllowedDockState = AllowedDockState.Docked Or AllowedDockState.Floating

This automatically will remove the caption buttons that may be responsible for an unwanted state, for example Closed. In addition, the unwanted menu items from the context menu will be disabled:

The following setting will disable the Floating option:

Disable the floating dock state

C#

toolWindow1.AllowedDockState = ~AllowedDockState.Floating; 

VB.NET

toolWindow1.AllowedDockState = Not AllowedDockState.Floating
