Pixel‑Accurate Component Previews
Kendo UI components in ThemeBuilder now match production output, reducing styling surprises so what you design is what users see across variants and interaction states.
Enhanced Customization
Templates have been enhanced to expose more parts, states and variations, giving designers and developers finer control over visual details without custom workarounds.
New Classic Components
New DropDownTree in Telerik UI for Blazor

Feature Improvements Beyond AI
Additional DataGrid Enhancements
Alongside the new smart features, this release brings developer‑focused improvements to the traditional DataGrid experience.
Features like CSV export, stacked layout modes and column min/max width constraints in KendoReact give more control over how data is presented and consumed.
The customizable keyboard shortcuts and improved sorting performance make the Telerik UI for Blazor Grid feel faster and easier to tailor to complex scenarios. Data interaction with grouping‑sort behavior allows grouped data to be reordered directly from the UI.
Chat UI Improvements Across the Board
Users can now quickly jump to the most recent messages with a dedicated scroll-to-bottom button. Message delivery is also more transparent with improved status indicators that can display text, icons or both, along with a new failed message state that allows users to easily resend messages with a single click.
Suggestions have also been refined. Clicked items can optionally disappear from the list and can now be inserted into the input for editing before sending.
These enhancements are powered by a more capable input experience, supporting single-line, multiline and auto-expand modes, customizable prefix and suffix content, and built-in actions like speech-to-text and file selection, making the Chat control more flexible, modern and user-friendly.
All these features make the component equally well suited for AI-to-human interactions and traditional human-to-human conversations.
Diagram Interaction Enhancements
You can now add text directly to connections with flexible positioning options, display tooltips on nodes and connections, and benefit from larger grab points that make starting new connections more precise.
Interaction is smoother with resizable connection segments, improved snapping between shapes and connectors, and automatic scrollbars when the canvas exceeds the viewport.
Additional upgrades such as keyboard navigation and resizable shapes contribute to a more polished and accessible diagramming experience.
New in Kendo UI for Angular Spreadsheet, Scheduler and PDFViewer
Angular Scheduler gains more flexible calendar control with options to show or hide days, weekends and other non‑working periods, along with improved slot styling.
The Angular Spreadsheet now enables Excel‑like filtering, sorting with visual indicators and comprehensive copy/paste/cut event handling.
Meanwhile, the Angular PDFViewer introduces support for form filling and blank pages and reuses the modern Toolbar component.
Telerik Reporting and Report Server Updates
With this release, Telerik reporting tools include inline image support in HtmlTextBox, repeat‑on‑every‑page table group headers, improved .NET‑based serialization and full Unicode BiDi text handling for accurate multilingual rendering—all designed to boost performance, readability and global accessibility. Developers also gain access to the downloadable .NET reporting source code, making debugging, customization and exploration easier.
Core Document Processing Enhancements
New MIME type support for embedded files allows developers to explicitly define how attachments like XML, JSON or CSV payloads are represented inside PDFs, while automatic file‑format detection makes it easier to load documents from byte arrays. Compliance is further improved through EU DSS‑aligned digital signing, helping validate PDFs against official European Commission standards. Additionally, Timestamp Server support in PdfStreamSigner enables trusted, verifiable timestamps that support long‑term signature validity.
Modern Framework Support and Integrations
