Yes, your example is working.

I had wrong view attached to the ExportDataToPdf function (I thought that it creates stream from current opened view).
Now it's partially working, but chart is missing. Check out images bellow. Chart is produced through javascript library Google.Charts. In the html code is showing as svg image.

this is an app:

this is a pdf output:

Have you seen something similar to this issue?
I can't post entire code to the repo, because I don't own rights.

Thank you.

Hi guys,

I have a problem with generating pdf report from ASP.NET Core app. I've followed this tutorial: https://jsreport.net/learn/dotnet-aspnetcore

Here is my code:

ExportController.cs

        [MiddlewareFilter(typeof(JsReportPipeline))]
        [Route("Export/ExportDataToPdf")]
        public async Task<IActionResult> ExportDataToPdf()
        {
            HttpContext.JsReportFeature().Recipe(Recipe.ChromePdf);
            HttpContext.JsReportFeature().OnAfterRender((r) => {
                using (var file = System.IO.File.Open("report.pdf", FileMode.Create))
                {
                    r.Content.CopyTo(file);
                }
                r.Content.Seek(0, SeekOrigin.Begin);
            });
            return View();

Startup.cs

  public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc()
        .AddSessionStateTempDataProvider();

            services.AddSession();

            services.AddMemoryCache();
            //services.AddDistributedMemoryCache();

            services.AddControllersWithViews()
                .AddNewtonsoftJson();

            services.AddJsReport(new LocalReporting()
                    .UseBinary(JsReportBinary.GetBinary())
                    .AsUtility()
                    .Create());


        }

Index.cshtml

   <input class="button .button-block pull-right" type="submit" value="Export" onclick="location.href=' @Url.Action("ExportDataToPdf", "Export")'" />

After returning a view from ExportDataToPdf() I get blank pdf document in the browser. Looks like content was not placed to the stream. Any ideas what am I doing wrong?
Thanks
