Need to update the check box value to db table when i click the checkbox() without post back in MVC2

Answer 1

$('#checkboxid').click(function(){
 $.ajax({ url: 'your_url_for_receiving_data',
type: 'POST',
data: { checkbox: $('#checkboxid').attr('checked') },
success: function(o) { alert('saved'); }
});

just create code behind in mvc2 where you will get value from request and save it to db
