How to disable docking but use pin/unpin feature?

Hi, Ram,

AllowedDockState property gives you the ability to determine the available dock states per ToolWindow. There are several options for this property that can be combined by bitwise operations. More information you can find here: https://docs.telerik.com/devtools/winforms/controls/dock/object-model/alloweddockstates 

In order to use the autohide function by clicking on the pin/unpin button you can use the following code snippet:

this.toolWindow1.AllowedDockState = AllowedDockState.Docked | AllowedDockState.AutoHide;

According to the context menu. RadDock uses ContextMenuService. Each context menu request is passed to the service, which on its hand creates the appropriate menu items and raises several events, which allows users to modify existing items, add their own or even cancel the request. When handling the ContextMenuDisplaying event you are able to cancel showing the context menu for the toolwindow by using e.Cancel=true. More information is available here: https://docs.telerik.com/devtools/winforms/controls/dock/architecture-and-features/using-the-contextmenuservice 

I hope this helps. If you have other questions do not hesitate to ask.

Regards,
Nadya
