ejReportViewer Export Problem When Using OWIN Authentication

[Vikas Patil]

I'm working on an HTML5/AngularJS web app that has a .NET WebApi backend.  We are using OWIN Authentication. We are using RDLC report for this app and data through web api. Reports are load/view/print done properly. But when I click on export button it throw error. We try your suggestion as per thread 119064, but not working. 

When I remove OWIN Authentication report exports properly.

I am attaching my sample project herewith. (Username - admin, Password - Admin)

Please guide us.

Thanks

So what is the status of this issue?

Hi Hasan, 

  

The mentioned issue “exporting the report using owin authentication in application” occurred due to override the WebAPi register method in owin startup.cs file. In which you may have registered WebAPI in both Owin startup class page and Global.asax page, hence the issue occurred. So, we request you to avoid registering WebAPI configure in owin startup class as shown in the following code snippet, 

  

Startup.cs  

        public void Configuration(IAppBuilder app)  

        {  

            HttpConfiguration config = new HttpConfiguration();  

  

            ConfigureOAuth(app);  

  

            //WebApiConfig.Register(config);  

  

            app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);  

            app.UseWebApi(config);  

        } 

  

Note:  If the issue still occurred, then please share us issue replicable sample using OWIN authentication. This may helpful to validate the issue from our side.
