    itemTemplate.css({ 'width': '100%', 'height': '450px' });
    itemTemplate.appendTo($(element));
    itemTemplate.ejReportViewer({
        reportServiceUrl: "../api/SSRSReport",
        processingMode: ej.ReportViewer.ProcessingMode.Remote,
        reportPath: "/SSRSSamples2/Territory Sales New",
        reportServerUrl: "http://76.74.153.81/ReportServer"
        });

Add WebApi Controller to the Server

LightSwitch HTML ReportViewer uses WebApi services to process the report file and also process the request from control.

Add References

You can add the following assembly references to Server project for WebApi and ReportViewer.

In the Server Project, right-click the References folder and then click Add Reference.
Add the following assemblies.

System.Web.Routing
System.Web.Http
System.Web.WebHost
System.Net.Http
System.Net.Http.WebRequest
System.Net.Http.Formatting
Syncfusion.Core.dll
Syncfusion.Linq.Base.dll
Syncfusion.EJ.ReportViewer
Syncfusion.ReportControls.Wpf
Syncfusion.ReportWriter.Base
Syncfusion.Pdf.Base
Syncfusion.XlsIO.Base
Syncfusion.DocIO.Base
Synfusion.Shared.Wpf
Syncfusion.Chart.Wpf
Syncfusion.Gauge.Wpf
Syncfusion.SfMaps.Wpf
Note:
Refer to System.Web.Http, System.Web.WebHost, System.Net.Http.WebRequest and System.Net.Http.Formatting dlls from ASP.NET WebApi nuget package.

Click OK.

Create WebApi Controller

Right-Click the Server Project, select Add > New Folder and name the folder Api.
Right-Click the Api folder and select Add > New Item.
In the Add New Item window, select Web API Controller Class and name it SSRSReportController.cs. Click Add.

Add Web API Controller Class

Inherit IReportController

The ApiController inherits the IReportController and adds the following code example to its methods definition to process the report file. The interface IReportController contains required actions and helper methods declaration to process the report. The ReportHelper class contains helper methods that help to process Post/Get request from control and return the response to control.

 [C#]
 
using Syncfusion.EJ.ReportViewer;
using System.Collections.Generic;
using System.Web.Http;
 
namespace LightSwitchApplication.Api
{
    public class SSRSReportController : ApiController, IReportController
    {
//Posts action for processing the rdl/rdlc report.
        public object PostReportAction(Dictionary<string, object> jsonResult)
        {
            return ReportHelper.ProcessReport(jsonResult, this);
        }
//Gets action for getting resources from the report.
        [System.Web.Http.ActionName("GetResource")]
        [AcceptVerbs("GET")]
        public object GetResource(string key, string resourcetype, bool isPrint)
        {
            return ReportHelper.GetResource(key, resourcetype, isPrint);
        }
//Calls method when initializing the report option before starting to process the report.
        public void OnInitReportOptions(ReportViewerOptions reportOption)
        {
            reportOption.ReportModel.ReportServerCredential = new System.Net.NetworkCredential("ssrs", "RDLReport1");
        }
// Calls method when report is loaded.
        public void OnReportLoaded(ReportViewerOptions reportOption)
        {
//Updates report options here.
 
        }
    }
}

WebApi Routing

Right-Click the Server Project, select Add > New Item and select Global.asax file from the listed templates.

Select Global Application Class

Figure 9: Adding Global.asax

You can route the WebApi in the Application_Start event into Global.asax file as follows.

[C#]
 
protected void Application_Start(object sender, EventArgs e)
        {
            System.Web.Http.GlobalConfiguration.Configuration.Routes.MapHttpRoute(
          name: "DefaultApi",
          routeTemplate: "api/{controller}/{action}/{id}",
          defaults: new { id = RouteParameter.Optional });
 
        }
