SortableDataView

[SrinivasaRaju Ch <sr...@sifycorp.com>]

Hi,

 How can i add a check box in the header column by using 
DefaultDataTable class , While using sortable dataview we have to pass
 IColumn[] columns as parameter to  DefaultDataTable class .
Ex:  DefaultDataTable<EmployeeDetails> dataTable =
                new DefaultDataTable<EmployeeDetails>("entries", 
columns, provider, 4);
                add(dataTable);

where columns is the IColumn[]  in which i have to place the headers . 
Now i want to place a check box in the header column as first column
followed by some other columns ex:
 IColumn[] columns = {
             
            new AbstractColumn<EmployeeDetails>(new 
Model<String>("CheckBox")){
                    public void 
populateItem(Item<ICellPopulator<EmployeeDetails>> cellItem, String 
componentId,
                        IModel<EmployeeDetails> model){
                        cellItem.add(new CheckboxPanel(componentId, model));
                    }
            },
            new PropertyColumn<EmployeeDetails>(new Model<String>("EMP 
ID"),"empId"),
            new PropertyColumn<EmployeeDetails>(new 
Model<String>("Employee Name"), "employeeName")
}

But i unable to place a check box as header in the above  code . Please 
tell me how to do it.
