At the moment it's only possible to have your reports in old-fashioned projects.
It should be possible to add/design reports to SDK-style projects. That should work no matter what target framework is (.NET Core, .NET Standard or .NET Framework).
Graphs do not render captions and labels properly when exporting to Excel, Word, or Powerpoint. The problem appears to be worse using Skia on Linux, but the problem is present with GDI rendering as well. Worth noting that PDF export works properly.
Here is an example report exported to Excel via a Linux Azure Web App and below that is the exact same report from the same environment as PDF:
Here is that same report as a PDF (which mirrors how it looks in the HTML5 viewer):
If we initialise the control in "FIT_PAGE_WIDTH" mode it essentially renders as expected but zooming in can actually then cause it to zoom *out*.
Reproducible in the `CSharp.NetFramework.Html5IntegrationDemo` example project as well, once you set the `scaleMode` property to "In FIT_PAGE_WIDTH".
In print preview, if you have "FIT_PAGE_WIDTH" as a default scale mode, once you click the "toggle full page/full page width" button, it's never possible to get it to return the original fit-page-width size (it seems to cycle between 3 different zoom modes, but none of them fill the entire control width).
It looks like the report viewer correctly sets the scale mode during initialization. However, when toggling the mode later, it sets it incorrectly.
I run an ASP.NET Core application that has the functionality to export reports into PDFs in an Azure environment.
There is no way to install additional fonts on Azure so I provide the fonts used in my reports via the "privateFonts" element of the Reporting configuration.
This works for the most part, the font is embedded in the produced PDFs but if I have a textbox with a large text, the text may be cut off when using the Skia engine.
I tested running my application in Docker, I copied the needed fonts in the usr/share/fonts directory of the Docker Linux container, and tried exporting again.
When exporting from Docker, with the fonts installed in the container, the text is not cut off. It seems that there is an issue when the fonts are provided as private fonts.
When exporting a report to Excel with the UseExtendedFormatting parameter set to False, the Standard DateTime Format Strings are hard coded as custom formats in the generated XLS/XLSX document.
The custom formats correspond to the current regional settings or, if the report is rendered with a specific culture, the default date format strings for the selected culture.
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.
This bug has been reintroduced in 2025 Q3: https://feedback.telerik.com/reporting/1671864-2024-q4-pdf-rendering-made-text-extraction-impossible
I use the font Roboto in a TextBox rotated vertically. The last character of the content is cut in the design time of the Standalone Report Designer. In Preview and when exporting to PDF, the content is displayed as expected.
Here is a link to a video showing the issue - https://somup.com/cTQjid8GRH
in this page, there are 3 languages. Vietnamese, English, Chinese, it display Vietnamese Messy code when download PDF.
pls hlep, thanks.
I am using the HTML5-based report viewer while connecting to a Report Server. However, the responses from the Report Server have a status code of 409 with the following error message:
Thе endpoint "Resources" is currently not accessible.
Some special characters, such as "🍁", break reports that are rendered with the Skia graphics engine in a Linux environment.
When the Gdi graphics engine is used on Linux, the reports are generated successfully. However, the Gdi graphics engine cannot be used on Linux with projects that target .NET 7 and later.
I am running the designer with the flag --roll-forward LatestMajor still getting an error in wizard when we try and open cs report
"Ensure that restore has run and that you have included 'net8.0' in the TargetFrameworks for your project."
When using the "Close"/"Close All" options when a report has unsaved modifcations, a warning is shown, but you are forced to save the report or close the window/tab to leave definition file unmodified.
A "close and discard changes" option is helpful and convenient - one can cancel some edits without hoping that a bunch of "Ctrl - Z" presses will clear everything, refer to one report without concern about accidental modifcations (can be editing others), etc.
We'd like to have a settable property on the web designer and report viewer which takes a function which returns an access token.
This way a new access token can be requested by the designer/viewer when the current one expires.
This is usually used in the following way:
Should the above be to specific/inflexible:
Instead of caching the access token, call AccessTokenProvider for every fetch but also provide an additional parameter with the "reason" for the call, so the implementer of AccessTokenProvider can decide themselves when to return a cached AccessToken or generate a new one.
I use the kendovalidator before rendering the report to check the correct parameter of initial and final date.
However, the validation fails because additional inputs (for the "Send Email" functionality) are included in the HTML output of the viewer even though I have disabled it.
I believe that if the "Send Email" option is disabled the mail data panel should not be created.
