public class NavigationBarRowScrollingElement

The NavigationBarRowScrollingElement is a TransformationBean™ that generates the appropriate HTML 4.0 and JavaScript to represents the row scrolling actions for a NavigationBar.

NavigationBarRowScrollingElement generates a HTML table which contains the row scrolling actions and the message associated with the NavigationBarRowScrollingElement.

This class requires a model that implements RowNavigationInterface.

The NavigationBarRowScrollingElement is one of several TransformationBeans™ that rely on a set of style classes that are used by default when generating the resulting markup language. For more information on style sheets and the default style classes that apply to this TransformationBean™, refer to the AppDev Studio Developer Site. You'll find a useful reference document entitled Cascading Style Sheets, Images, and TransformationBeans™ as well as the TransformationBeans™ Style Sheet Reference.

The NavigationBarRowScrollingElement is one of several TransformationBeans™ that rely on JavaScript to provide some of its functionality. These JavaScript files are including automatically by the tbean. See JavaScriptIncludeHandler for more information about how these files are included and how to customize this behavior. The NavigationBarRowScrollingElement uses the following JavaScript files:

sas_navigationbar.js

Note that the toString() method on this class calls the write method, which may have undesirable side effects. See BaseTransformation.toString() for more information. Debuggers often use toString() to show the value of a variable, and this may cause unexpected behavior while debugging

For More Information:

Visit the AppDev Studio Developer's Site to access step-by-step examples, white papers and additional usage information at http://support.sas.com/rnd/appdev/.

Examples for this class may be found on the Examples Site.

JSP custom tags provide an alternative to using the TransformationBeans™. Visit the Custom Tag Library Reference for additional information on the sas:NavigationBarRowScrollingElement custom tag.
