Release History

Progress® Telerik® Reporting 2024 Q1 (

January 31, 2024

Note for an upcoming change

  • This release is the last one that delivers assets supporting .NET Framework 4.0 - 4.6.1, .NET Core 3.1, and .NET 5 applications. The next 2024 Q2 release will support applications targeting .NET Framework 4.6.2+ and .NET 6+.

Enhanced Installation Process

  • The installation process has been improved for better user experience.

OpenXML rendering formats now support DocumentFormat.OpenXML SDK 3.0.1 or newer for both .NET Framework 4.0 and .NET Standard 2.0

  • Telerik Reporting rendering engine now creates DOCX, XLSX, and PPTX documents referencing DocumentFormat.OpenXML SDK 3.0.1. This functionality is available in assembly files targeting .NET Framework 4.0 and .NET Standard 2.0, and a NuGet package targeting .NET Standard 2.0.

Enable WPF, WinUI, and WinForms report viewers to show reports rendered by a remote reporting service that uses Skia graphics engine

  • This release brings SkiaSharp-based rendering for WPF, WinUI and WinForms based applications, that are working with REST service hosted under Linux using Skia graphics engine. The supported extensions are XAML, XAMLInteractive, WPFXAML, WPFXAMLInteractive.

The Standalone Report Designer now targets .NET 8

  • Standalone Report Designer for .NET now can benefit from the performance improvements introduced with .NET 8. It also allows to load user assemblies that target .NET 8 and earlier versions of the framework.

Move Column Right/Left functionality added for tables in Web Report Designer

  • Selected table columns can be moved using the new context menu functionality "Move Columns > Left/Right" for tables with static column groups.

Ability to add Native Angular viewer component using npm schematics package

  • Our npm schematics package now enables users to add native Angular Report Viewer component in Angular 15, 16, and 17 applications.

Extensive customization of the Preview functionality in Web Report Designer

  • We extended the Web Report Designer's client-side API to allow passing report parameter values and any other settings to the integrated Report Viewer. Using the new 'startMode' initialization setting, you can also start the designer in preview mode directly allowing to embed the designer instead of a viewer control and this way to empower your end users to preview reports and switch to design view only in case they need it.

The Value editor for HtmlTextBox item in Web Report Designer now uses a KendoUI Editor component

  • We have replaced the component for editing the Value property of the HtmlTextBox item. Instead of using a plain-text editor, the users now can write and preview their HTML in a KendoUI Editor component, having instant visual feedback on how their HTML will look like in the rendered report.
