Type Parameters:
T - Model object type
All Superinterfaces:
IClusterable, IDetachable, Serializable
All Known Subinterfaces:
IColumn<T,S>, IExportableColumn<T,S>, IFilteredColumn<T,S>, IStyledColumn<T,S>, ITreeColumn<T,S>
All Known Implementing Classes:

public interface ICellPopulator<T> extends IClusterable, IDetachable
Represents an object that is capable of populating an Item container representing a cell in a DataGridView with components.

Example 

 class NamePopulator implements ICellPopulator
 {
        void populateItem(final Item cellItem, final String componentId, final IModel rowModel) {
       User user=(User)rowModel.getObject(cellItem);
       String name=user.getFirstName()+" "+user.getLastName();
       cellItem.add(new Label(componentId, name);
     }}
In this example the IDataProvider assigned to the DataGridView retrieves User objects from the database. The cell populator adds a label to the cell that will display the full name of the user.
