Release 2026 Q2 (20.1.26.707)

I use the exportBegin event to prevent the default export logic. However, when I do that, the default viewer notification remains, and I have to hide it manually:

                    exportBegin: function (e, args) {
                        args.handled = true; // Set to true to cancel the default export behavior.
                        //...
                        $(".trv-notification").addClass("k-hidden");
                    },

Hi there,

Adding an external style sheet to a report in a report-book triggers an error when previewing the report book, "Object reference not set to an instance of an object" 

I've attached the bare minimum project to reproduce the error.

I've also tried upgrading to R3 2020

Cheers

In my Graph, I have set the AccessibleRole and AccessibleDescription. The alternative text is read correctly by the Acrobat Reader's 'Read out Loud' functionality.

The problem is that it keeps reading it multiple times.

In Chromium browsers such as Edge and Chrome, if I have set PDF files to always be downloaded from the browset content settings, and I click on the print button in the toolbar, the print dialog is never displayed, nor is the PDF downloaded.

The Import Code File Wizard incorrectly displays a warning in a non-English locale despite the build completing successfully. The warning appears to be triggered by localized culture settings and does not reflect an actual build issue.

Double-click selection in the expression editor isn't context-aware. In almost every other application, double-clicking selects a token based on its surrounding context — a single field/identifier when clicking on a field, or the word boundary within a string literal when clicking inside quotes. The expression editor doesn't respect these boundaries, so its double-click behaviour is inconsistent with the standard expression-editor behaviour users expect.

Expected: Double-click selects the relevant token based on context (e.g. an individual field reference, or a word within a string literal).

Actual: Double-click selection ignores context and does not match the token/word-boundary behaviour found in virtually all other expression editors and text inputs.

When using screen reader applications like JAWS or Narrator, those tools read accessible reporting PDFs in an incorrect order. For example, if I have two items in the report, the reader will read the second item first.

Additionally, images whose AccessibleDescription I have set may be read multiple times..

I have graphs in my report. I render them with Skia on Linux. The issue reproduces with Skia on Windows as well.

The legend labels are not aligned well with the color icon, and data labels on a horizontal bar chart (with OutsideEnd) are misaligned as well:

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.

After an upgrade, I get an exception in my WinUI report viewer. Interestingly, if I continue through the exception, the report viewer does display but has an invalid license background. The invalid license seems to cause the exception.

Release 2026 Q2 (May)

When I display a report in a web report viewer, whose service is running on a server where one or more of the used fonts are not available, the first instance of the item(s) that use those fonts is being substituted with another font. The rest of the items do render with the original font, however.

This creates confusion and inconsistency. We should use the substituted font because it's used for measuring when using Print Preview mode in the web viewers, or when rendering to pdf via print/export.

Hi Team,

 

Even after giving the date format facing the inconsistency in the date field for some rows in the table when we export it to CSV file

<TextBox Width="1.036in" Height="0.24in" Left="0in" Top="0in" Value="= Fields.StartDate" Format="{0:MM'/'dd'/'yyyy h:mm tt}" Name="Opened Date">. please see the attachment

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 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.

I am trying to use the following HTML content for the HtmlTextBox item:

<span style="font-weight:bold">Label&nbsp;1:</span>&nbsp;<span>Data&nbsp;1</span> <span style="font-weight:bold">Label&nbsp;2:</span>&nbsp;<span>Data&nbsp;2</span>

However, the non-breaking space between the spans (label 1/data 1 and label 2/data 2) is not preserved.

I have a custom assembly with default 'version', 'culture', and 'publicKeyToken'.

When I reference the assembly in the 'assemblyReferences' element only with its 'name', the Reporting Engine recognizes it.

If I reference it with the full version, '1.0.0.0', it also works.

However, when I set the 'version' to '1.0.0', the Reporting Engine throws, stating that the assembly is not trusted and must be referenced in the 'assemblyReferences' element.
