public abstract class DataView

extends DataViewBase

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