Remarks
A contents view is a tab in the table of contents. ArcMap ships with two contents views: Display (TOCDisplayView) and Source (TOCCatalogView). Create custom contents views by implementing the IContentsView interface. Only one contents view can be active at a time. This property returns the number of contents views registered in the ESRI Contents Views component category. The Display contents view is not listed here as it is the default.
