How to create ActionResult for "Details" functionality in internet application of MVC 4.0?
Model-View-Controller is a very vast topic hence I try to cover it in small articles. I have developed this code using Microsoft Visual Studio - Ultimate Edition 2012 and with the help of MVC4.0
Razor engine is used in this.
Significance and usage of ActionResult:
Description:
Always its controller's duty to convey ASP.NET MVC Framework to show the view by returning a ViewResult.
ActionResult indicates the next steps that should be taken to process the request.Every controller action is expected to provide the return value.
using System;
using System.Collections.Generic;
using System.Net;
using System.Net.Http;
using System.Net.Http.Formatting;
using System.Net.Http.Headers;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using yournamespacename.Models;
namespace yournamespacename.Controllers
{
public class yourControllername : Controller
{
yourclassname obj = null;
[HttpGet]
public ActionResult Details(int id)
{
var obj_client = new HttpClient();
var obj_task = obj_client.GetAsync("http://localhost:yourportnumber/api/your_controller_name/" + id.ToString())
.ContinueWith((task_readresult) =>
{
var response = task_readresult.Result;
var obj_read_asyn = response.Content.ReadAsAsync
obj_read_asyn.Wait();
obj = obj_read_asyn.Result;
});
obj_task.Wait();
return View(obj);
}
}
}
You can either set the return type as JsonResult or simply it will be ActionResult.
Json() It returns a JsonResult which serializes an object and renders it in JSON format.
