export function not return

[nedim]

Hello,

Reportviewer show report  normally  but when  request any export  service return  below  error report , 

 xmlns:q1="http://www.w3.org/2001/XMLSchema" xmlns:p2="http://www.w3.org/2001/XMLSchema-instance" p2:type="q1:string">

Sf_Exception - System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary. at System.Collections.Generic.Dictionary`2.get_Item(TKey key) at Syncfusion.EJ.ReportViewer.ReportHelper.ProcessReport(Dictionary`2 jsonResult, IReportController reportController)

i think problem is sending parameters , when call report show, run parameters :

{"reportAction":"ReportLoad","controlId":"tekneler_reportViewer_Control","reportPath":"Tekneler.rdlc","reportServerUrl":"","processingMode":"Local"}

but when call  export mode, i see parameters  not json  format:

controlID=22B2E0A3-20E5-622A-47EE-2189D60FDB9D%40tekneler_reportViewer_Control&resourcetype=PDF&isPrint=false&reportName

when  debug our api i see in reportviewer controller ,  PostReportAction functions  Dictionry parameters empty, when calling export.

sorry for poor english.

Hello, 

I think problem is wep.api  handling/routing.

I use previously downloaded  x:\Syncfusion\15.3.0.26\JavaScript\ejservices\App_Data\Reports\Product Catalog.rdlc  fro test.

I run  x:\Syncfusion\15.3.0.26\JavaScript\ejservices   web.api  service in local, and syncfusion angular 2 example offline (sample report path routed to local server)  ,  no problem. I see report and  I get export content.

But when use our web api  , report show, report print  is ok,  but when requesting  export to any options, request goes to controller, I see with debugger , but not return export content.

     Our  web.api  version  2.0 and use  .net 4.5.1 . and config route is,

            config.Routes.MapHttpRoute(

                name: "ActionApi",
                routeTemplate: "api/{controller}/{action}",
                      defaults: new {action= RouteParameter.Optional}
                );

Hi Nedim, 

We suspect the mentioned problem might be occurred when export dependent assemblies are not referred in your WebAPI application. So, we request you to refer the ReportViewer export dependent assemblies in your application. Also, please ensure the same build version and framework version assemblies are referred in your application. Please find the list of Syncfusion ReportViewer dependent assemblies, 

• Syncfusion.Linq.Base
• Syncfusion.Compression.Base
• Syncfusion.Presentation.Base
• Syncfusion.OfficeChart.Base
• Syncfusion.EJ
• Syncfusion.EJ.ReportViewer
• Syncfusion.Pdf.Base
• Syncfusion.XlsIO.Base
• Syncfusion.DocIO.Base
• Syncfusion.Shared.Wpf

Hello Again,

Thank your support.

I download this base  projects and compiled, report  show  ok, but Export function returns error.

I spent a lot of time, but I failed in the export process.  :( 

AngularSample: http://www.syncfusion.com/downloads/support/directtrac/general/ze/AngularSample-153486040.zip  

Reportservice: http://www.syncfusion.com/downloads/support/directtrac/general/ze/ReportingService39913430.zip  ,

  HTML code for report:

<h1>
    {{title}}
</h1>
   <ej-reportviewer id="territorysales_reportViewer_Control" [reportServiceUrl]="serviceUrl" [processingMode]="localMode"  [reportServerUrl]="serverUrl"

    [reportPath]="reportPath" [dataSources]="reportData" [parameters]="parameters">
</ej-reportviewer>

TS code for report:

import { Component, ViewEncapsulation, ViewChild } from '@angular/core';
import { EJComponents } from 'ej-angular2';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
   title = 'app works 2!';

    public serviceUrl: string;
    public serverUrl: string;
    public localMode : string;

    public reportPath: string;
 public parameters: any;
 public reportData: any;

    constructor() {
        this.serviceUrl = 'http://localhost:49771/api/ReportApi';
          this.reportPath = 'Product Catalog.rdlc';
         this.localMode = 'Local';

       
    }  
}

my sample api  attached, it use  syncfusion  standart report example   Product Catalog.rdlc  and sample List data retuns.

Hi Nedim, 

Thanks for the update. 

We have checked the mentioned export problem in the shared sample and its working properly at our end. We suspect the mentioned problem might be occurred when different build version and framework version of Syncfusion dependent assemblies are referred in your application. So please ensure the same build and framework version Syncfusion dependent assemblies are referred properly in your application. 

If the issue still persists, then share the issue reproducible screenshot and RDL file to validate the mentioned problem at our end.
