I use the SRD.NET connected to RS.NET. When I attempt to create a new report on RS.NET, I get the following error, as it creates a 0-byte TRDP file:

When a report is saved in the Web Report Designer, a popup appears confirming that the report was successfully saved. However, it is visible for far too long and blocks users during this time.

This feature request is to add an 'ok', 'hide' or 'close' button to these types of popups so the user can dismiss it.

Thank you,

Shannon

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.

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

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");
                    },

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.

It would be great if you could introduce the ability to create custom reusable color palettes in Telerik Report Designer, so I don't have to declare the same set of colors for each chart I need them.

If you have a lot of graphs in your report then it is more convenient to change the color palette one place.

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.

Release 20.0.26.424

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.

If I open the expression dialog in the Web Report Designer and select one of the available functions, I will see a sample snippet in the third column below the expression area.

This column is not selectable, so I cannot copy the example and test it out. This example should be copyable, so that each function can be easily tested in the report designer.

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

Product/version: Telerik Reporting 19.0.25.313 (Telerik.Reporting.Cache.StackExchangeRedis)

  Request:
  Add a RedisStorage constructor overload that accepts StackExchange.Redis.IConnectionMultiplexer rather than only the concrete ConnectionMultiplexer.

  Current behavior:
  new RedisStorage(ConnectionMultiplexer connectionMultiplexer) requires the concrete type.

  Problem:
  Modern ASP.NET Core apps manage a single shared multiplexer through DI and expose it as IConnectionMultiplexer — the abstraction recommended by StackExchange.Redis, and the same type
  Microsoft.Extensions.Caching.StackExchangeRedis uses via its ConnectionMultiplexerFactory (which returns IConnectionMultiplexer). To call RedisStorage we are forced to downcast our IConnectionMultiplexer back to
  ConnectionMultiplexer. This is fragile and it prevents passing test doubles or decorators (e.g. for instrumentation/logging).

  Proposed change:
  Add RedisStorage(IConnectionMultiplexer connectionMultiplexer), plus a databaseNumber overload (RedisStorage(IConnectionMultiplexer connectionMultiplexer, int databaseNumber)). ConnectionMultiplexer already
  implements IConnectionMultiplexer, so this is fully backward-compatible — existing callers that pass a concrete instance keep working unchanged. Everything RedisStorage needs is available on the interface
  (GetDatabase for string operations and LockTake/LockRelease, GetSubscriber, GetServer).

  Benefits:
  - Clean dependency-injection integration with a shared, app-managed multiplexer.
  - Unit-testability via a mocked IConnectionMultiplexer.
  - Consistency with StackExchange.Redis guidance and Microsoft's own caching abstractions.

  Note:
  Please target the maintained Telerik.Reporting.Cache.StackExchangeRedis package (the .2 variant appears discontinued after 18.2.24.806 and has no 19.x/20.x release).
