Starting in 2019, the Reporting control is no longer included in Essential Studio. If you're experiencing issues with the Syncfusion Reporting Platform, Report Viewer, Report Designer, or Report Writer, we recommend migrating to Bold Reports, our dedicated reporting platform.

Bold Reports offers a comprehensive suite of tools and features for all your reporting needs, and we will help you make a smooth transition from the discontinued control. Our support team at https://support.boldreports.com/ is here to assist you with any questions or difficulties you may encounter during the migration process.

We thank you for choosing Syncfusion and appreciate your understanding.

The controller for path '/api/ReportApi/PostReportAction'; was not found or does not implement IController.

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)

   en System.Web.Mvc.DefaultControllerFactory.CreateController(RequestContext requestContext, String controllerName)

   en System.Web.Mvc.MvcHandler.ProcessRequestInit(HttpContextBase httpContext, IController& controller, IControllerFactory& factory)

   en System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()

   en System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

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

But I will now present another problem, the report view
