# AllowedDockStates

**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
```
