Hi,

I have created one Standalone report with an Object Person (Which contains properties Name, Number and DOB).

Then, I'm using below code to generate PDF from this report.

            var reportProcessor = new ReportProcessor();
            var deviceInfo = new System.Collections.Hashtable();

            var reportSource1 = new UriReportSource();
            reportSource1.Uri = "/report.trdp";
            var reportSource = new InstanceReportSource();
            var report = new Telerik.Reporting.Report();
            var objectDataSource1 = new Telerik.Reporting.ObjectDataSource();
            objectDataSource1.DataSource = new Person() { DOB = DateTime.Now, Number = 1293737, Name = "test" };
            objectDataSource1.Name = "PersonDataSet";
            report.DataSource = objectDataSource1;
            reportSource.ReportDocument = report;
            reportSource.ReportDocument.ReportSources.Append(reportSource1);

            RenderingResult result = reportProcessor.RenderReport("PDF", reportSource, deviceInfo);

            string fileName = result.DocumentName + "." + result.Extension;
            string path = System.IO.Path.GetTempPath();
            string filePath = System.IO.Path.Combine(path, fileName);

            using (System.IO.FileStream fs = new System.IO.FileStream(filePath, System.IO.FileMode.Create))
            {
                fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
            }
        }

But, It generates only empty report.

Can anyone help me to resolve this?

Thanks,

Hi,

I am new to telerik reporting.   I have designed sample report.

i have added a crosstab , linegraph in detail section .

My datasource has 3 rows  I get 6 pages of output.

But I am expecting only single page output.

Kindly help me here.

Hello,

Can someone please point me to some sample code having a master/detail section such as is found on a purchase order or invoice that is using ASP.NET Core 3.1 or better? I can't quite seem to see how to get both of the data source hooked up properly when using an ObjectDataSource.

Thank you,

Hi,

I have a .Net 5.0 RC2 Blazor WebAssembly application with System.Text.Json as json de/serialization support. I configured server project to serve reports, but I receive the error:

Property 'JsonResult.SerializerSettings' must be an instance of type 'System.Text.Json.JsonSerializerOptions'.

It is obvious that the error appears because the NewtonsoftJson package is missing - but I don't want to replace System.Text.Json de/serializing mechanism. The question is: is there a way to override/provide the json serializer settings and to skip this issue?

Thanks,

Ion

Hi,

I want to add one straight line (the pink one from the image) on my bar series. How to do it?

Telerik reporting version 11.1.17.614, using visual studio 2015

I am implementing a REST service with a custom report source resolver. There will be a single instance of the service.

For the IStorage interface implementation, which one offers better performance, FileStorage or MsSql Database storage? The load may be high, hundreds of reports in the same time.

For FileStorage, if I don't specify any location, what is the defaul location on the file system?
