    DataView is a basic implementation of AbstractPageableView. Data views aim to make it very simple to populate your repeating view from a database by utilizing IDataProvider to act as an interface between the database and the dataview.

    Example: 

         <tbody>
       <tr wicket:id="rows">
         <td><span wicket:id="id">Test ID</span></td>
         ...

    Though this example is about a HTML table, DataView is not at all limited to HTML tables. Any kind of list can be rendered using DataView.

    And the related Java code: 

     add(new DataView<UserDetails>("rows", dataProvider)
 {
        public void populateItem(final Item<UserDetails> item)
        {
                final UserDetails user = item.getModelObject();
                item.add(new Label("id", user.getId()));
        }
 });
