This is again related to your other posts. Instead of having an empty TabbedMdiContainer defined in the TabbedMdiHost (which is bad), just have the TabbedMdiHost.

When you create a DocumentWindow, do NOT use the parameterless constructor. The documentation for that says to never use that constructor when creating DocumentWindows programmatically. Use the other constructors that accept the DockSite parameter, etc.

Create and activate your document window like this:

DocumentWindow documentWindow = new DocumentWindow(dockSite, name, title, image, textBox);
documentWindow.Activate();

That will work as expected.
