checkbox1State = get(handles.checkbox1, 'Value');
checkbox2State = get(handles.checkbox2, 'Value');
checkbox3State = get(handles.checkbox3, 'Value');

and so on.

Thanks. I have read the help document about this issue. And I can determine the current state of a check box from within its callback by querying the state of its Value property .

if (get(hObject,'Value') == get(hObject,'Max'))
  % Checkbox is checked-take appropriate action
  handles.chexkbox1 = 1
else
  handles.ckeckbox1 = 0;
end
