## Class AbstractDataGrid

- java.lang.Object
- - javax.faces.component.UIComponent
  - - javax.faces.component.UIComponentBase
    - - org.richfaces.component.UIDataAdaptor
      - - org.richfaces.component.UISequence
        - - org.richfaces.component.AbstractDataGrid

- All Implemented Interfaces:
    EventListener, javax.faces.component.NamingContainer, javax.faces.component.PartialStateHolder, javax.faces.component.StateHolder, javax.faces.component.TransientStateHolder, javax.faces.component.UniqueIdVendor, javax.faces.event.ComponentSystemEventListener, javax.faces.event.FacesListener, javax.faces.event.SystemEventListener, javax.faces.event.SystemEventListenerHolder, Row, org.richfaces.ui.common.meta.MetaComponentEncoder, org.richfaces.ui.common.meta.MetaComponentResolver, org.richfaces.ui.iteration.IterationStateHolder
  Direct Known Subclasses:
    UIDataGrid

      public abstract class AbstractDataGrid
      extends org.richfaces.component.UISequence
      implements Row, org.richfaces.ui.common.meta.MetaComponentResolver, org.richfaces.ui.common.meta.MetaComponentEncoder

  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.
