org.apache.wicket.markup.repeater.data.DataView
DataView is a basic implementation of AbstractDataView. Data views aim to make it very simple to populate your repeating view from a database by utilizing {@link 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())); } }); 
```
