A TabStrip is a control that contains a collection of one or more tabs.
Each Tab of a TabStrip is a separate object that users can select. Visually, a TabStrip also includes a client area that all the tabs in the TabStrip share.
By default, a TabStrip includes two pages, called Tab1 and Tab2. Each of these is a Tab object, and together they represent the Tabs collection of the TabStrip. If you add more pages, they become part of the same Tabs collection.
