Type Parameters:

T - Model object type

public class DataGridView<T>
extends AbstractDataGridView<T>

Simple concrete implementation of AbstractDataGridView

Example:

           <table>
             <tr wicket:id="rows">
               <td wicket:id="cells">
                 <span wicket:id="cell"> </span>
               </td>
             </tr>
           </table>
 

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

And the related Java code:

  // Application specific POJO to view/edit
  public class MyEntity {
    private String firstName;
    private String lastName;

    // getters and setters
  }

  public class MyEntityProvider implements IDataProvider<MyEntity> {
      ...
  }

 List<ICellPopulator<MyEntity>> columns = new ArrayList<>();
 
 columns.add(new PropertyPopulator<MyEntity>("firstName"));
 columns.add(new PropertyPopulator<MyEntity>("lastName"));
 
 add(new DataGridView<MyEntity>("rows", columns, new MyEntityProvider()));
