Create a grid with all rows selected at opening

[alessalessio]

I searched through the forum ,but actually i didn't find a solution to this.

I have a Grid with a certain number of records and a CheckBoxSelectionModel.
What i want to do is to see all the rows selected after the grid is rendered.


Actually, this is the code i use but does not do to job.

Grid<ModelData> grid = new Grid<ModelData>(TestData.getStore(), TestData.getColumnModel());

final CheckBoxSelectionModel<ModelData> sm = new CheckBoxSelectionModel<ModelData>();
sm.setSelectionMode(SelectionMode.SIMPLE);

grid.setSelectionModel(sm);
grid.selectionModel.selectAll();

I tried to fire the event Events.HeaderClick after setting the selection model but it doesn't fire at all

Where is the mistake?


thanks for the help

Seems that the only way to do this is only when the Grid is attached ..

    @Override
    protected void onAttach()    {
        super.onAttach();
        selectionModel.selectAll();
    }

Here it works.
