Gets or sets whether end-users can dock and undock panels by dragging them.
true to allow end-users to dock and undock panels; otherwise, false.
Use the FreezeLayout property to control whether an end-user can change a panel's dock state, and rearrange panels within a zone by dragging them. Set the FreezeLayout property to true to prohibit an end-user from changing the docking layout.
The setting of the FreezeLayout property doesn't affect the ability of docking/undocking a panel via code.
