  I added a DocumentContainer control with multiple DocumentWindows at design time, and I'd like to prevent closing or reordering the document windows.
  
  So far, I set the DocumentButtons property to None, and I found a post on here to disable the right-click context menu.
  
  However, in testing, users could still click the tab with their third mouse button / clickable scroll wheel and close a document window; I need to prevent this. Also, how do I prevent users from dragging tabs around to rearrange their order? I'd like to keep them in the order I chose at design time.
  
  Thanks to anyone with an answer!

  Anyone know how to disable closing / reordering tabs in a DocumentContainer control, inside a RadDock?

  Hi Grant,
  
  Thank you for writing.
  
  I am getting straight to your questions:
  1. How to prevent users from closing DocumentWindow.
  You can do that by subscribing to the DockWindowClosing event of RadDock and cancel the operation if the window that is being close is of type DocumentWindow:
  

  void radDock1_DockWindowClosing(object sender, Telerik.WinControls.UI.Docking.DockWindowCancelEventArgs e)

  {

      if (e.NewWindow is DocumentWindow)

      {

          e.Cancel = true;

      }

  }

  
  2. Is there a way to prevent users from dragging tabs around to rearrange their order? 
  Yes there is. To prevent the different docking operations, simply stop the DragDropService and to prevent the items from being rearranged set the ItemDragMode of the TabStripElement to None:
  

  DragDropService service = this.radDock1.GetService<DragDropService>();
service.Enabled = false;

documentTabStrip1.TabStripElement.ItemDragMode = Telerik.WinControls.UI.PageViewItemDragMode.None;

  
  I hope that the provided information addresses your questions. Should you have any other questions, do not hesitate to contact us.
   
  All the best,
