What's New 2026 Q1

ASP.NET MVC PromptBox: Elevated Prompt Input Experience

The new Telerik UI for ASP.NET MVC PromptBox component provides a dedicated input area for composing and sending prompts to AI models. It adapts to different prompt lengths with flexible sizing options and supports file attachments, speech-to-text button and input adornments, making it easy to build rich, conversational AI experiences.

ASP.NET MVC SmartPasteButton: Effortless Input Filling

The new Telerik UI for ASP.NET MVC SmartPasteButton lets users paste unstructured text, e.g. an email signature, message, or snippet, and convert it into structured data. The component sends the pasted content to an AI service, interprets the information, and automatically fills in the matching input fields. This eliminates repetitive copy‑and‑paste steps and makes data entry faster, cleaner, and more intuitive.

ASP.NET MVC Smart Grid: Semantic Search Built into a SmartBox

The Telerik UI for ASP.NET MVC DataGrid introduces AI Semantic Search – a meaning‑based way to find what you need, even when keywords don’t match exactly. Instead of relying on exact text, Semantic Search understands intent and context, surfacing the most relevant rows across columns and related fields. It’s ideal for large datasets where users might not know the precise terms or spelling.

Complementing this, the new AI Smart Box provides a single, streamlined place to run Semantic Search and ask AI‑assisted questions. Users can search by meaning, then immediately refine, filter, or ask follow‑up questions within the same interface.

ASP.NET MVC Smart Grid – AI Chat Integration

The Telerik UI for ASP.NET MVC Grid now integrates seamlessly with the ASP.NET MVC AI Chat capabilities, giving users a conversational way to explore and interact with Grid data. Instead of relying on manual filtering and navigation only, users can ask natural‑language questions that the Chat Assistant interprets using the Grid’s schema, context, and current view. This makes data discovery faster, more intuitive, and accessible even to users who are unfamiliar with the underlying structure of the dataset.

Refined ASP.NET MVC Chat for a Cleaner, More Intuitive UI

The Telerik UI for ASP.NET MVC Chat component receives a series of visual and usability enhancements that make chat conversations clearer, more polished, and easier to follow. Message metadata now aligns cleanly on a single line with status indicators, and the header has been modernized by replacing the AppBar with the Toolbar component for a more consistent look and feel. The Chat also adopts the new PromptBox control for a richer prompt‑input experience, while attachment menus and download buttons have been refined with a smaller visual footprint. Pinned messages now stay sticky for better visibility, and suggestion lists introduce new scroll buttons with gradient styling for smoother browsing.

More Precise Diagramming in Telerik UI for ASP.NET MVC

The Diagram now offers more interactive editing experience with connector text, tooltips, and improved connection handling through larger grab points, resizable segments, and better snapping. Users also benefit from dynamic scrollbars, full keyboard navigation, and resizable shapes, making diagram creation smoother and more flexible than ever.

Document Processing Libraries 2026 Q1 Enhancements

• [Preview] Agentic tools: Build intelligent document processing workflows with ease. The DPL Agentic Tools let users extract structured data, edit content, convert formats, generate new Excel or PDF files and perform analysis on Excel documents directly inside your .NET app with no separate services required.
• Core enhancements: New MIME type support for embedded files allows you 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, ensuring PDFs meet official European Commission validation standards. Additionally, Timestamp Server support in PdfStreamSigner enables trusted, verifiable timestamps for long‑term signature validity.
