Examples of org.richfaces.component.AbstractDataGrid

org.richfaces.component.AbstractDataGrid

The <rich:dataGrid> component is used to arrange data objects in a grid. Values in the grid can be updated dynamically from the data model, and Ajax updates can be limited to specific rows. The component supports header, footer, and caption facets.
