Background documentation Standard Library of UI Elements Locate the document in its SAP Library structure

Web Dynpro allows a design-oriented development of user interfaces and provides a comprehensive class library of UI elements for application programming.

UI elements can be used within a Web application to execute actions, display and enter text or display graphics. Buttons, checkboxes, and radio buttons are typical UI elements, for example. Some of the UI elements provided by Web Dynpro can automatically execute generic services.

When developing the Web Dynpro applications, the UI elements are placed in a view displayed in a specific screen area at runtime. Web Dynpro supports not only the modelling of the view contents but also the navigation between the individual view contents within the Web application. 

Each UI element has different properties and events that determine the appearance and behavior of the UI element on the user interface. A detailed description of the properties and actions that are associated with a specific UI element can be found on the following pages. Select one of the UI elements listed below.

List of Standard UI Elements

The class library of UI elements contains abstract and concrete UI element classes. Abstract classes are used to provide common characteristics for concrete classes. Abstract classes cannot be instantiated. Only concrete classes can be instantiated and their instances can be placed in a view during the application development.

By default, Web Dynpro provides the following concrete UI elements:
