I'm new using Syncfusion.
I'm trying to make an example following documentation

Load RDLC Reports

This is my view.

@using Syncfusion.JavaScript
@using Syncfusion.MVC.EJ

    ViewBag.Title = "Index";
<div style="width:100%">

        .DataSources(ds => ds.Name("DataSetCapitulo").Value(ViewData["Capitulo"]).Add()))


@section styles{


@section scripts{
    <script src="~/Scripts/Reportes/jquery.easing.min.js"></script>
    <script src="~/Scripts/Reportes/ej.web.all-latest.min.js"></script>
    <script src="~/Scripts/Reportes/ej.unobtrusive-latest.min.js"></script>

This is my controller

using Interventorias.Entities;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace Interventorias.Controllers
    public class ReportController : Controller
        private InterventoriasEntities db = new InterventoriasEntities();

        // GET: Report
        public ActionResult index()
            ViewData["Capitulos"] = db.sp_capitulos(1);
            return View();

This is my api

using Syncfusion.EJ.ReportViewer;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Security;
using System.Web.SessionState;
using System.Web.Http;

namespace Interventorias.api
    public class ReportApiController : ApiController, IReportController
        //Post action for processing the rdl/rdlc report
        public object PostReportAction(Dictionary<string, object> jsonResult)
            return ReportHelper.ProcessReport(jsonResult, this);
        //Get action for getting resources from the report
        public object GetResource(string key, string resourcetype, bool isPrint)
            return ReportHelper.GetResource(key, resourcetype, isPrint);
        //Method will be called when initialize the report options before start processing the report
        public void OnInitReportOptions(ReportViewerOptions reportOption)
            //You can update report options here
        //Method will be called when reported is loaded
        public void OnReportLoaded(ReportViewerOptions reportOption)
            //You can update report options here

This is my Global.asax.cs

public class MvcApplication : System.Web.HttpApplication
        protected void Application_Start()

            System.Web.Mvc.ModelBinders.Binders.Add(typeof(decimal), new DecimalModelBinder());
            System.Web.Mvc.ModelBinders.Binders.Add(typeof(decimal?), new DecimalModelBinder());
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{action}/{id}",
            defaults: new { id = RouteParameter.Optional });

And this is the error that occurs:

[HttpException]: The controller for path &#39;/api/ReportApi/PostReportAction&#39; was not found or does not implement IController.

   en System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(RequestContext requestContext, Type controllerType)

Thank you very much,
Sorry for my English

Hello Yuvaraj D.

Thanks, solved the above problem, it was just a matter of adding the class WebApiConfig hehe
