I have above checkbox when i select the this i need to update the DB table without post back. Please explain.. If possible you can say jquery or ajax method to solve my pro开发者_运维百科blem
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:
<form action="/MyApp/HandleClick/" method="post">
<input type="checkbox" name="SelectedObject" value="cbValue"/>
<button type="submit">Submit</button>
</form>
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.
$('#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
" />
in controller
public ActionResult(string value) { return View();
} it is help you
