I have a Telerik Reporting Library 2019 project which contains Telerik Reports. The reports are consumed from a ASP.NET Core web application when controller actions are called. So there is a reference to this Reporting library project from Web project.
In the web project I create a ReportBook to generate report. and render the report as a PDF.
[HttpGet("{reportId}", Name = "Report")]public async Task<IActionResult> Get(Guid reportId){ //Report Book var reportBook = new ReportBook(); var instanceReportBookSource = new InstanceReportSource { ReportDocument = reportBook }; //Cover Page var coverPageReportSource = new InstanceReportSource(); var coverPagereport = new CoverPage(reportId) { DocumentName = "Cover Page Report" }; coverPageReportSource.ReportDocument = coverPagereport; reportBook.ReportSources.Add(coverPageReportSource); var reportProcessor = new ReportProcessor(); var renderingResult = reportProcessor.RenderReport("PDF", instanceReportBookSource, new Hashtable()); var fileName = renderingResult.DocumentName + "." + renderingResult.Extension; var path = Path.GetTempPath(); var filePath = Path.Combine(path, fileName); using (var fs = new FileStream(filePath, FileMode.Create)) { fs.Write(renderingResult.DocumentBytes, 0, renderingResult.DocumentBytes.Length); } var output = renderingResult.DocumentBytes; return File(output, "application/pdf");}
In the reports I have few PictureBox components. I want to set pictures from a http url (https://docs.telerik.com/reporting/report-items-picture-box#data-binding)
Example
1.var pictureBox = ((Telerik.Reporting.PictureBox)(reportDef.Items.Find("pictureBox1", true)[0]));2.pictureBox.Value = "https://d585tldpucyb98b4-413e94c0e92bvanemkallan.jpg"; //Some Image URL
But when I try to do that it always gives an error (report-error.png). Is this because I have report definition in one project and consuming it from another project (web project). How can I solve this.

Hi. I have error page. (attached file)
We have four servers. only 1 server has this problem. All settings are same. I couldn't find any differences.
The report page has just a small circle shape.
I used default Html5ReportViewer1.html and aspx form which is created by Visual Studio new file menu.
When I use fiddler I got this message with URL /api/reports/clients.
{"message":"An error has occurred.","exceptionMessage":"개체 참조가 개체의 인스턴스로 설정되지 않았습니다.","exceptionType":"System.NullReferenceException","stackTrace":"

Hi,
I have a report with lot of columns. I need to show it with the fixed font size(8px) and horizontal scroll bar in HTML Report Viewer. But when I try to render the report, the report shrinks(it tries to fit in the container). How can I render the report without shrinking it and with horizontal scroll bar
Regards,

I create my report form and it can export docx file (click preview mode and select export with "Word Document").
but after I resize textbox43 to fit content, it get the corrupt docx file. How can I solve this problem .

I recently upgraded by ASP.Core beta web project to an ASP.NET Core 2.0 application with an ASP.NET Core 2.0 API behind it.
Before the upgrade, my Telerik reports ran fine.
Now, the HTML5 viewer appears, and throws the following error:
"Error registering the viewer with the service. An error has occurred. The type initializer for 'Lock' threw an exception."
In Chrome developer's console, the following javascript error shows:
1#:1 Uncaught (in promise) Invalid cliendID
Promise.then (async)
refreshReport @ telerikReportViewer-12.0.18.227.js:1442
start @ telerikReportViewer-12.0.18.227.js:5417
I have followed the exact steps from here to support ASP.NET Core 2.0 apps:
https://docs.telerik.com/reporting/html5-report-viewer-asp-net-core-2#html5-report-viewer-in-asp-net-core-2
Any ideas what the error means and how to fix it?
Thanks!
