The DevExpress Bootstrap Controls suite ships with a set of layout controls allowing you to build complex adaptive user interfaces.
The Page Control displays content as a set of tabbed pages. Each page in the Page Control serves as a separate child control container allowing you to associate specific page content with each displayed tab.
The Popup Control provides the ability to create and use a number of popup windows in your web application. Popup windows are a special type of overlapped temporary window that appear separately from an application's main window, and are typically used to display quick reference information.
