UltraTabControl is designed as a replacement for the Microsoft supplied tab control. As such it automatically creates a tab page child control (UltraTabPageControl) for each tab. The tab page is used to contain controls that are unique to each tab. UltraTabControl exposes all the functionality of the inbox Tab control plus many new features including support for mnemonics, hiding and disabling tabs, shared controls, multiple tabs styles and orientations (including wizard and note page styles). UltraTabControl offers all of the functionality of ActiveTabs as well.
UltraTabStripControl exposes all of the features of the UltraTabControl except that it doesn’t create an UltraTabPageControl for each tab. Therefore the only thing that changes visually when a new tab is selected is the tab header area.
