Hi Chiranjiv, 
 
We suspect the mentioned problem might be occurred when the exported dependent assemblies are not referred properly in your ASP.NET Core API service application. So can you please ensure the below ReportViewer dependent nuget file are installed properly at your end.  
  • Syncfusion.EJ.ASPNET.Core
  • Syncfusion.EJ.ReportViewer.AspNet.Core
  • Syncfusion.Licensing
 
If we install the above NuGet packages, it automatically add the below ReportViewer dependent NuGet file in your application, 
  • Syncfusion.EJ
  • Syncfusion.Compression.Net.Core
  • Syncfusion.DocIO.Net.Core
  • Syncfusion.Pdf.Net.Core
  • Syncfusion.Report.Net.Core
  • Syncfusion.XlsIO.Net.Core
 
For your reference, we have shared a API service sample, RDL report used in the service and exported PDF file, which can be downloaded from below location, 
 
So can you please replace your RDL file in above shared service sample and if the issue still persists, then share the issue reproducible RDL file to validate the mentioned problem at our end.

Hi Chiranjiv, 
 
On further analysis of the shared screenshot, it shows the export process call the PostReportAction API method. But in ASP.NET Core application when the export process occurs it will call the PostFormReportAction API method. So can you please confirm which application you are using for Web API at your end, since PostReportAction API method will not be called in ASP.NET Core application. Hence if you share your issue reproducible sample and it would be helpful for us to validate the mentioned problem at our end.

Hello there,

Any update for above issue??

MM Mageshyadav M Syncfusion Team October 10, 2018 02:39 PM UTC

Hi Chiranjiv, 
 
Export is not working 
On further analysis of the shared Angular sample, the mentioned problem occurs when you have referred the older version Syncfusion JavaScript file in Package.json file. So can you please upgrade to the latest version (16.3.21) as shown in below screenshot, 
 
 
 
We have modified the shared Angular sample and it can be downloaded from below location, 
 
Default parameter is not specified for the hidden parameter.  
Also you have not specified the default value for the hidden parameter. So can you please specify the default value for the hidden parameter as shown in below code example, 
 
    constructor(public http: Http, 
                private authSercice:AuthenticationService) { 
 
                    this.authSercice.getData() 
                    .subscribe( 
                     (response) => { 
                            
             
                          this.reportPath='/Reports/employee.rdl'; 
                          this.serviceUrl = 'http://localhost:53800/api/ReportApi';     
                          this.reportData = JSON.parse(response._body);    
                            this.parameters = [{ 
                                                name: 'myToken',  
                                                labels: ['Test'],  
                                                values: ['Test'],  
                                                nullable: false  
                          }];  
                          console.log(this.reportData); 
                          this.flag=true; 
                          
                         }); 
                          
 
            // var currentUser=JSON.parse( localStorage.getItem('currentUser')); 
 
            // this.Role=currentUser["_body"]; 
 
    } 
 
Please refer to the below UG documentation link for more detail, 
   
Specifying the default value for the parameter will not work in ASP.NET Core 
 
We have an issue in specifying default value for parameter in latest version (16.3.0.21) Nuget packages and we have fixed this issue at our end. So a support incident to get the patch for this issue has been created under your account. Please log on to our support website to check for further updates.
