[.NET] Show and hide ArcCatalog tabs in runtime

Is it possible to show and hide ArcCatalog tabs (e.g. "Preview" or my custom IGxView) in runtime?

For example, I have a toolbar with button in ArcCatalog. I click the button and tab "Preview" (or "Contents, or another) is hiding from the ArcCatalog tab control. When I click the button again, the tab shows up.
