Dear community,

I have a license for Telerik_Reporting_R2_2020_SP2_14_1_20_814_DEV, I didn't use reports for long time but I have an application that requires it. I use Visual Studio Community 2022 Version 17.8.6 and tried to re-install report but I still cant find a way to include a trdp file created with Report Designer R2 2020 in my newly created ASP.NET MVC app. I had a look on the internet but still facing this problem.

Is there someone who can guide me to solve this issue.

in advance, many thanks
Ray

We are experimeting a very slow perfomance when render report to xlsx format from version 17.2.23.1114 using .Net 7, render to pdf is perfect.
With Telerik 15.2.21.915 version report was fast using .net 5 

Test environment (.net 7 under linux container)
- api .net 7
- running in Linux Container. Pod Kubernetes
- nuget Telerik.Reporting (18.0.24.130)
- nuget Telerik.Reporting .OpenXmlRendering3 (18.0.24.130) with DocumentFormat.OpenXML 3.01 -DocumentFormat.OpenXml.Framework 3.0.1
- nuget Telerik.Reporting .WebServiceDataSource (18.0.24.130)
- nuget Telerik.Drawing.Skia (18.0.24.130)
- dockerfile includes next lines:
       RUN apt-get update
       RUN apt-get install -y libfreetype6
       RUN apt-get install -y libfontconfig1

We have this code to generate the report

 var reportSource = new InstanceReportSource { ReportDocument = _report };
 var reportProcessor = new ReportProcessor();
 var renderingResult = reportProcessor.RenderReport(format.ToString().ToUpper(), reportSource, null);
 var telerikReport = new DocumentResult(renderingResult);
 return telerikReport;

When we use format="XLSX" RenderReport is very low, when use PDF in the same report time is perfect.

In last versions of Telerik, 15.2.21.915, perfomance with XLSX was perfect the same API but in .net 5

What can we do?

Hi team support,

I was assigned to a project using telerik.reportviewer.webhtml Version=7.1.13.612. As of last week, someone reported a vulnerability bugs of bgColor parameter. 

I've read some articles saying that it has to be upgraded to version 11.0.17.406 (2017 SP2) or later. 
My question is, can I replace telerik.reportviewer.webhtml.dll file with the newest dll only? 
And what about the dependencies? This is the current version of .NET & MS used.

I have no support from the vendor built because the project was really old.
I'd appreciate any help. Thankyou.

Hello Team,  

I have a report that contains 2 images. one jpg --> base64   and one PDF --> base64. I use expression to fill the value for the picture Box controls as shown below. 

When I run the report the PDF image is missing. I also tried to paste the B64 text, but it didn't work. I'm I missing a step?   

Using Report Designer version 17.2.23.1010.  .NET Framework 4

I updated my front end package.json to use the Telerik Angular Report Wrapper, and the backend to use Telerik.Reporting 17.2.23.1114 trial:

From the browser, when trying to access the backend `ReportsController` (.Net 4.6), I get the following exception:

<ExceptionMessage>Multiple actions were found that match the request: Formats on type SynWAPI.Controllers.ReportsController GetClientsSessionTimeoutSeconds on type SynWAPI.Controllers.ReportsController Version on type SynWAPI.Controllers.ReportsController</ExceptionMessage>
<ExceptionType>System.InvalidOperationException</ExceptionType>

Now generally when I send a test request to the old version of TelerikReports (14.x) from https://MyApp01.MySite.com/MyApp/api/reports, I get the following response in the browser (however in my upgrade envir it's throwing the above exception):

[{"name":"PDF","localizedName":"Acrobat (PDF) file"},{"name":"CSV","localizedName":"CSV (comma delimited)"},{"name":"XLS","localizedName":"Excel 97-2003"},{"name":"RTF","localizedName":"Rich Text Format"},{"name":"IMAGE","localizedName":"TIFF file"},{"name":"MHTML","localizedName":"Web Archive"},{"name":"XPS","localizedName":"XPS Document"}]

In my Angular component html, I'm using the Telerik Wrapper:        

<tr-viewer
    [serviceUrl]="serviceUrl"
    [reportSource]="reportSource"
    [viewMode]="'INTERACTIVE'"
    [scaleMode]="'SPECIFIC'"
    [scale]="1.0"
    [templateUrl]="templateUrl"
>
</tr-viewer>

and my `ReportsController` on the backend (.net 4.6)

    }
}

I can't seem to resolve this issue. Do you have further examples online, or any advice for me here ?

thanks,
