Thank you for writing. Hidden panels are stored in the ManagedDockables collection and also in the saved XML layout. Please use the GetManagedDockables method of the DockingManager in the following way:
|foreach (IDockable dockable in mDockingManager.GetManagedDockables()) |
|if (dockable.ID.Equals(equipmentID)) |
| return(DockPanel)dockable; |
I hope this helps. If you have any additional questions, please contact us.
All the best,
the Telerik team
