How to call partial view through ajax in mvc3 - ajax

Question

I need to call a partial view through ajax. I have tried the following, but I am not sure how to complete it.
$("#UserName").change(function () {
var userid = $("#UserName").val();
var ProvincialStateID = $("#State").val();
var Hobbyid = $("#Hobby").val();
var Districtid = $("#DistrictNames").val();
var Homeid = $("#Hobbyhome_EstablishmentId").val();
var urlperson = '#Url.Action("FetchPersonByUserName")';
$.ajax({
type: "POST",
url: urlperson,
data: { userid: userid, stateid: ProvincialStateID, hobbyid: Hobbyid, districtid: Districtid, homeid: Homeid },
success: function (data) {
//Dont know what to write here
});
});
Here is the function that I have written in my Controller:
[HttpPost]
public ActionResult FetchPersonByUserName(int userid,int stateid,int districtid,int homeid,int Hobbyid)
{
//Code to fetch the data in the partial using all parameters
return PartialView("_LearnerAssociationGridPartial", list);
}
When I click on a dropdown the ajax gets called and I want the function which is called through ajax to redirect it to the partial view. Please help me because currently I am not able to display my partial view

Answer 1

What you need is something like
$.ajax({
type: "POST",
url: urlperson,
data: { userid: userid,
stateid: ProvincialStateID,
hobbyid: Hobbyid,
districtid: Districtid,
homeid: Homeid },
success: function (data) {
var result = data;
$('targetLocation').html(result);
}
});
it is recomended to not use data straight from variable but you can.
Now target location is where you want the result to be displayed to.
See more information in here:

As to slow fetching data, try optimalize your query
Update
For nhibernate running slow, try http://www.hibernatingrhinos.com/products/nhprof which is nhibernate profiler, for paid version, or try sql profiler to see what is query is beeing executed, often you can get much more that you would expect and or really slow query due to complexity of the query.

I dont understand what you mean by redirect to the parial view. Usually people use ajax and Partial views to get part of a page without a page refresh ( you might have seen this kind of behaviour in this site/facebook/twitter etc..) So i guess you probably want to show the data you are fetching asynchronosly to be shown in a part of your current page. you can do that in your success handler
$.ajax({
type: "POST",
url: urlperson,
data: { userid: userid, stateid: ProvincialStateID, hobbyid: Hobbyid, districtid: Districtid, homeid: Homeid },
success: function (data) {
$("#divUserInfo".html(data);
}
});
Assumung you have a div with id divUserInfo in your current page.
If you really want to redirect after the ajax post, you can do it like this.
$.ajax({
type: "POST",
url: urlperson,
data: { userid: userid, stateid: ProvincialStateID, hobbyid: Hobbyid, districtid: Districtid, homeid: Homeid },
success: function (data) {
window.location.href="Why-I-need-Ajax-Then.php";
}
});
Personally, I dont use HttpPost (both in client and server) If it is a method to GET some data. I simpy use the jquery get or load.
$.get("yourUrl", { userid: userid, stateid: ProvincialStateID } ,function(data){
$("#divUserInfo".html(data);
});
