selectionModel.setSelected(object, false); only deselects the currently selected row. Add a FieldUpdater to the Column containing the CheckboxCell, in which you reset the value of the checkbox on the specific condition. datagridTable.redraw() updates the view.

Edit: Looks like redraw() doesn't update the value of checkbox. Manually updating the value of CheckBoxCell should work. See updated code.

Pseudo-Code:

checkboxColumn.setFieldUpdater(new FieldUpdater<DataGridObject, Boolean>() {

    @Override
    public void update(int index, DataGridObject object, Boolean value) {
        if(specificCondition) {
            object.setCheckboxValue(false);
            checkboxCell.setViewData(object, false);
            datagridTable.redraw();
        }


    }
});
