I'm using    JsonConvert.SerializeObject(ds)  to convert to JSON string     dataset composed of three tables   the resulting JSONcomes back with something the result shown below.  These fields are part of header section in the report and they are giving me errors.  Someone suggested to remove the square brackets in order to make it work and it did the trick.  Is there a way I can access these fields in the header section without making changes to the resulting JSON?  

hi,

    I would like to ask, why does Telerik Report request the /info api multiple times? Can this info interface be requested in other ways to reduce the number of times?

thanks.

Hi everyone,

I'm having an issue with Telerik Report Viewer (HTML5 version) and Telerik Report Designer. I'm trying to change the database connection dynamically, and although the new connection string is being passed correctly (I’ve confirmed this by printing the in-memory values), the report viewer keeps using the initial connection and doesn't apply the new one.

What's even stranger is that after clearing cookies, browser data, and restarting the site, it still sticks to the first connection it received. It feels like Telerik stores this connection internally (maybe through caching or some static variable) and won’t allow it to update.

Has anyone experienced something similar or knows how to force the viewer to use the new connection?
Any suggestions or guidance would be greatly appreciated.

Thanks in advance.

I'm using ReportProcessor in my .NET 8 project to render a trdp report.  Rendering in PDF works fine but when I try to render as XLSX I'm getting the error in the subject line.

I've triple checked that I have installed all dependencies per this article OpenXML and XPS options not visible. Unavailable rendering format - Telerik Reporting

Any suggestions?

        [Authorize]
        public IActionResult Export(long id, string reportName="Statement.trdp", string format="PDF")
        {
            var baseUrl = $"{Request.Scheme}://{Request.Host}{Request.PathBase}";

            var reportProcessor = new ReportProcessor();
            
            var uriReportSource = new UriReportSource
            {
                Uri = Path.Combine(_environment.ContentRootPath, "Reports", reportName)
            };

            uriReportSource.Parameters.Add(new Telerik.Reporting.Parameter("stmtId", id));


            uriReportSource.Parameters.Add(new Telerik.Reporting.Parameter("url", baseUrl));

            var result = reportProcessor.RenderReport(format, uriReportSource, null);

            return File(result.DocumentBytes, result.MimeType);
        }

I have a report with three parameters - two drop-downs and a date. All have AllowNull set to False.

The two drop-downs work fine when I pick data, but the Date parameter still has the red mandatory asterisk even though I have selected a date from the calendar - see below

What am I doing wrong?

Thanks

Tim.

Can I run the VS report designer in a .net 8 Class Library project?

I can do it with .net 4.8 but not with standard nor .net 8?

I am trying to replicate ssrs reports into telerik, and I need to have a Table layout like,

   column title         column title          column title

subtitle subtitle        subtitle            subtitle subtitle

  data      data              data                  data      data

can that be done from the webreportdesigner?

Hey forum members, 

My company recently decided to move the apps from IIS to Kubernetes. We had some issues with fonts but we solved. Telerik can render pdf succesfully but we see some shifts on texts and spaces in words get bigger. It renders on IIS on windows server fine, but in docker container, it seems weird a bit. We could not the reason. 

I m attaching the screenshots.
Note: all the data in the attached pictures are test data. They are not valid.

What is your suggestions about the cause? 

Thanks
