When the WinForms Report Viewer is initialized from within the Form.Load Event, and the RefreshReport() method of the viewer is invoked before it is added to a parent form, the following exception will be thrown:
Telerik.ReportViewer.WinForms.Licensing.UiLicensePresenter.ShowWatermark(Action showWatermarkCallback) at Telerik.ReportViewer.Common.TelerikLicensePresenterBase.PresentWatermark(Action showWatermarkCallback) at Telerik.ReportViewer.WinForms.WinViewer.OnPaint(PaintEventArgs eventArgs) at System.Windows.Forms.Control.PaintWithErrorHandling(PaintEventArgs e, Int16 layer) at System.Windows.Forms.Control.WmPaint(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(HWND hWnd, MessageId msg, WPARAM wparam, LPARAM lpa
I am rendering reports locally using the report processor. When I use the RenderReport method after processing MS Office Documents and PDF files with the Spire. Office, it causes the text of the report rendered with Telerik Reporting to get truncated:
using Telerik.Reporting;
Spire.Doc.Document document = new Spire.Doc.Document();
var wordDocPath = "./wordtest.docx";
var pdfFilePath = System.IO.Path.Combine("../../../", "wordtest.pdf");
document.LoadFromFile(wordDocPath);
Spire.Doc.ToPdfParameterList toPdf = new Spire.Doc.ToPdfParameterList();
//toPdf.AutoFitTableLayout = true;
document.SaveToFile(pdfFilePath, toPdf);
document.Close();
var reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
var reportPackager = new ReportPackager();
string sourceReportFile = "./Static Broken CSU Analysis.trdp"; ;
using (var sourceStream = System.IO.File.OpenRead(sourceReportFile))
{
var report = (Report)reportPackager.UnpackageDocument(sourceStream);
var deviceInfo = new System.Collections.Hashtable();
var reportSource = new InstanceReportSource();
reportSource.ReportDocument = report;
Telerik.Reporting.Processing.RenderingResult result = reportProcessor.RenderReport("PDF", reportSource, deviceInfo);
if (!result.HasErrors)
{
string fileName = result.DocumentName + "." + result.Extension;
string filePath = System.IO.Path.Combine("../../../", fileName);
using (System.IO.FileStream fs = new System.IO.FileStream(filePath, System.IO.FileMode.Create))
{
fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length);
}
}
}If I comment out the section that is converting the totally unrelated word file to pdf and run it again, it does not clip.
The data source of my report contains grouping string values, among which are the '10000' and '1010Q'. These two values are always treated as the same string, and the corresponding records fall within the same report group, which is unexpected:
When I open a tab that includes the Angular report viewer and close it immediately after, before the viewer can be properly initialized, the following error will be thrown:

When the report contains SVG images with Arc segments, the rendering with Skia may result in the following exception:

If I set both the "EnableAccessibility" and "ViewerRenderToolTips" device info settings to true, the generated PDF document is corrupted.
When importing a report with the Standalone Report Designer for .NET, if the report or its items use report events, they are not automatically imported into the TRDP file.
It is currently necessary to manually type the method names in the corresponding properties in the report designer.
Hi Support team,
On ServerSide, when using a CultureInfo, with a NumberSeperator different then '.', e.g. CultrerInfo("de-DE"), it is not possible to Save a report.
It seems it is internally converted to a string based value and gets the different seperator and than can not be casted/converted back to double.
Best regards

Steps To Reproduce:
- Install Reporting.
- Go to \Tools folder.
- Start DatabaseCacheConfigurator.exe
- Leave the first combobox to 'Create engine viewers/cache database'
- Paste a valid connection string in the textbox below, e.g. Data Source=.\sqlexpress;Initial Catalog=AdventureWorks;Integrated Security=True
- Click on Create Schema or Clear Cache Data.
Expected behavior: The function is executed
Actual behavior: A message saying "Operation could destabilize the runtime." is shown.
I use an approved government font for the reports. I have specified it in the `privateFonts` option of the report engine configuration. However, on Linux, it is not picked up during rendering. In FontForge, the font shows the following warning:
On Windows, it causes no issues.
Visual Studio 2022, Telerik Reporting 2025 Q2, Visual Studio Designer, C# code, running VS as admin, VS version is Microsoft Visual Studio Professional 2022 (64-bit) - Current Version 17.14.13 (August 2025)
A few days ago, the data explorer window stopped functioning, while it seems to be around the same time of the last VS update, I'm not 100% sure. The data explorer window just does not populate at all, appears to not update the screen at all (so you see whatever was there). I have tried system restarts, repair install on Telerik Reporting, closed the data explorer window and opened it again, searched for possible answers - nothing. I can run the report in Preview so the data connection is fine. Attached is a screenshot of when I open the Data Explorer - as you can see while the data explorer window shows, the contents is what was there previously. If I leave it open and restart VS the window comes up all white. This is happening for all reports (14 in this project).
Only VS extensions installed are AWS Tookit and Telerik.
VS is not showing any errors in the output window, the option for "Show output from", at least initially, has no entries for Telerik
I cannot localize the messages of the Angular and React report viewers using the suggested approaches:
- Angular Report Viewer Localization - Telerik Reporting
- Localizing the React Report Viewer - Telerik Reporting
The only alternative is to use the approach from the Localization of the HTML5 ReportViewer Explained - Telerik Reporting article, which I can do only by loading the string resources script in index.html of the SPA.
I have updated to version 19.2.25.813 of Reporting, and when I try to build a project that has Reporting references, I get the following warnings:
Telerik and Kendo UI Licensing warning TKL102: Your current license has expired and is not valid for Telerik Document Processing Libraries version 2025.2.807.20.
There are no Telerik Document Processing dependencies in my project, but I still get the warning.
I am currently working on adapting our documents to meet EAA accessibility requirements, and I have upgraded Telerik Reporting to version 19.2.25.813.
I added { "EnableAccessibility", true } to the device information settings when exporting to PDF.
However, when I run the generated PDF through the PAC accessibility checker, it reports the following error:
One or more checks could not be completed. Please copy the error message and send it by email to pac@axes4.com so that we can improve the product.

The problem doesn't occur if I upgrade to an older Reporting version.
