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

Answer 1

You have to do some sort of request back to the server, whether it's a POST from a form button or an Ajax POST or GET request.

Form button:

    
    Submit

Or, Ajax (with jquery):

 jQuery('input[name=SelectedObject]').click(function() {
     jQuery.ajax({
         url: '/MyApp/HandleClick/',
         data: {
             SelectedObject: this.value,
         }
         success: function() {
             // Process success data...
         }
     });
 });

Then your controller:

public class MyAppController : Controller
{
    [HttpPost]
    public ActionResult HandleClick(string value)
    {
        // Handle persisting value to database...

        // If posting
        return RedirectToAction("OtherAction");

        // If Ajax
        return Json("Success!");
    }
}

That's the simplest example - can't answer more without more details about exactly what you're trying to accomplish.
