I have a CS report that contains a SubReport with InstanceReportSource. I have it in a .NET 10 Classlibrary project.

I tried to edit this report as a coded report in SRD.NET. However, when I saved the report, in the 'designer.cs' file, the value assigned to the ReportSource of the SubReport was set to 'userreport1' that is not instantiated and throws.

Currently, when you set SplitWorksheetOnPageBreak to True, the Excel Sheet name is formed from the DocumentName or ReportName and the number of the page.

It would be very helpful if the report authors can manipulate these names with Expressions.

I have localized a report with a Graph in the 'ar-SA' culture.

When exporting to PDF from the viewer, the report is generated as expected. In the Report Viewer's Preview, though, the Graph Legend and Labels are not correct:

I am using Native Blazor Report Viewer, but the problem also reproduces in the HTML5-based web viewers, with all the themes I have tested.

Currently, if I want to see what the device info settings for an extension like the PDF are, I need to open the documentation - Telerik Reporting Configuring the Output Formats PDF Device Information Settings - Telerik Reporting, then copy the setting that I wish to use in my code.

It would be easier and safer if the device information settings for each format were exposed as a public enum/class. On that note, it would also be easier if the available formats were exposed as well, instead of manually typing them. For example:

public static classTelerikDeviceInfoSetting
{
    public static class PDF
    {
        public const string DOCUMENTTITLE = "DocumentTitle";
        public const string DOCUMENTAUTHOR = "DocumentAuthor";
        public const string DOCUMENTSUBJECT = "DocumentSubject";
        public const string DOCUMENTPRODUCER = "DocumentProducer";
        public const string DOCUMENTCREATOR = "DocumentCreator";
    }

    public static class XLSX
    {
        public const string USENATIVEPAGEHEADER = "UseNativePageHeader";
        public const string USENATIVEPAGEFOOTER = "UseNativePageFooter";
        public const string SHOWGRIDLINES = "ShowGridlines";
    }
}

public static class TelerikRenderingExtension

{

public const string PDF = "PDF";

public const string XLSX = "XLSX";

}

The Telerik.Reporting documentation mentions that the Telerik.Reporting.* libraries should be available on nuget.org with the most recent release. However, when I search for Telerik.Reporting in the NuGet Gallery, I am not able to find any Telerik.Reporting.* package. The other products we use (UI for WPF, Document Processing) seem to be available though.

-----------------------------------------

Staff note: On the Reporting side, our initial goal was indeed to make Telerik Reporting available through nuget.org, alongside the rest of the Telerik product portfolio. However, we are currently investigating an issue that is preventing us from publishing the Telerik.Reporting packages to nuget.org, which has delayed their availability.

Please use this feedback item to subscribe to updates and receive a notification as soon as the Telerik.Reporting packages become available on nuget.org.

Telerik Reporting 2026 Q1 (20.0.26.211) fix to 'Paged report layout now supports repeatable table group headers/footers' is not working when embedded table (within a parent embedded table) spills on to the next page. The parent-embedded-table does not repeat in the header.

The attached sample has a simple table with two row groups, and "header" rows created via "Insert Row -> Outside Group - above".
The groups have "keep together" set.

But despite this, the header rows render at the bottom of one page, with data rows on the following page. This should never happen, I can't think of any case it would be expected (it would be like having "Chapter 2" at the bottom of a page when the text for it starts on the next page). 

I also have a sample with just 1 row group, but with 2 detail rows, and the same thing happens. It only appears to work when there's just 1 row group and 1 detail row.

I am using the HTML5 report viewer and seeing 4 errors in the WAVE tool, along with multiple alerts. See: https://wave.webaim.org/report#/https://demos.telerik.com/reporting/product-sales

Please consider addressing them.

When generating PDF/UA files, we need to have special objects that are read by an internal system but ignored by screen readers. This cannot be achieved with the existing functionality.

It would be beneficial if we could configure reports so that specific objects inside the generated document are ignored by screen readers. For example, by setting a special value to the AccessibleRole property of a text box.

The Group Footer rows of my table are displayed thinner than the rest of the table rows in PDF rendering. However, they are designed the same as the Group Header Rows and the Detail rows.

I am using the Standalone Report Designer for .NET to open a code-based report from an application that was migrated from .NET Framework. Before the migration, function calls defined in the designer.cs file were preserved and evaluated at runtime as expected. However, after migrating to the code-based reports functionality supported by the Standalone Report Designer for .NET, these function calls are evaluated immediately during the report import process, and the resulting values are then serialized and stored in the report definition.

It would be nice if the function calls were preserved in the imported report, allowing them to be evaluated later at runtime, as their return values may change depending on the execution context.

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).

When I export a report to MS Word that includes a bullet list and one of the items in the list spans two pages, the item gets two bullets in MS Word: one on the first line of the bullet, which is correct, and on the first line of the bullet that appears on the next page. This second bullet should not appear. The attached screen shot shows what I mean.

Our clients enter information using the radeditor and in many cases want to embedded tables and graphics into their text.  Using your reporting tool there is no way to print this information.  I know you have suggested using your table and image tools, but that doesn't work when you are dealing with freely formatted text so the existance and location of the tables and images cannot be predicted.

My Data Explorer shows "No Data Source" and empty field list, where prior to this, the fields were correctly listed.

I just recently updated to the latest reporting release  2025 Q1 in addition to updating to the newest Visual Studio Community 2022 (64-bit) - Current
Version 17.13.2

I installed the newest reporting update and updated my VS project.

I must have at least 50 different reports which I have previously designed and have been working fine.  The DataSource is set to the object exposing all the key fields using gets.  Works fine when running the program but after all the updates, all of a sudden I can see, in the designer, the fields in the fields list when editing an element value reference or in the the Data Explorer. 

Played with a sample element in the detail panel.  The form has the data source set correctly.  The toolbox also shows the reporting tools.  No go.

I verified the new reporting DLL is intact.

Same situation with all my reports.  All work fine running, just the designer interface is not working.

I even tried on another computer, also updated, and experienced the same problem.

Again, now all my reports don't show the list - something intrinsically has changed. with the setup and recognition of the DS.

The Initialize method in ReportViewer.cs is called from both the OnLoaded and OnApplyTemplate methods, which in turn calls the AttachModelEventHandlers method. This leads to it adding the event handlers to the model twice every time it is loaded. The DetachModelEventHandlers is only called once (in the OnUnloaded method), so if you keep unloading and reloading the control, it adds 2 event handler invocations but removes only one. This means each one is called at least twice (if you have only loaded the control once), then 3, 4, 5, etc times if you keep unloading and reloading it.

I've worked around this by adding code to my wrapper class to prune the duplicated handlers for now, but this needs fixing in the base code.

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.

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.

The Web Report Designer does not entirely comply with CSP standards, necessitating the use of the 'unsafe-eval' directive in our CSP policies to enable its functionality.

This directive poses significant security risks and undermines the purpose of implementing CSP in the first place. Please remove this requirement.
