I am developing a Web Application with Asp.NET MVC5. As I dont have much experience, I am stuck with a functionality using JQuery and Partial View.

I have a Side Menu as a partial view in a page. This partial view contains a DropdownList which is populated from model, and it works fine. However, I want to display a list of items from the db when the dropdown is selected, based on the selection, which is not working.

Partial View (_UserPartialView)
var item = $(this).val(); 
$.get("/Controller/GetItems/" +  item, function(data)

public ActionResult (int id)
   var test = db.Users.Where(e => e.cId = id);
   return PartialView(" _UserPartialView", test);
Please help.
