Description

When you add/show a new document, it is placed considering the RadDock.DocumentManager.DocumentInsertOrder property. The default value is DockWindowInsertOrder.InFront. Hence, the documents are placed in front. In other words, when you make visible a DocumentWindow, it is located at first position. Then, when you make visible each next DocumentWindow, it is placed in front of the previously added/shown window. This behavior is by design.

Solution

You can change the order of the tabbed documents by using the DocumentTabStrip.Controls.SetChildIndex method passing the desired window and index. Here is a sample code snippet which result is illustrated below:

            this.documentWindowOverview.CloseAction = Telerik.WinControls.UI.Docking.DockWindowCloseAction.Hide;

            this.documentWindowArchive.DockState = Telerik.WinControls.UI.Docking.DockState.Hidden;
            this.documentWindowOverview.DockState = Telerik.WinControls.UI.Docking.DockState.Hidden;
