Hello everyone,
Here are the highlights of the new online resources we published this week from 10 Nov 2025 to 17 Nov 2025:
Article: https://www.telerik.com/kendo-react-ui/components/grid/smart/selection
Summary: Learn how to use Smart Selection in the KendoReact Grid to manage row or cell selection that remains consistent across virtualization, paging, sorting, filtering, and grouping. The article shows how to enable the mode, configure single/multiple and checkbox selection, and implement a controlled selection state via selection-change callbacks on the client or server.
Article: https://www.telerik.com/kendo-react-ui/components/migration/assisted-migration
Summary: Use KendoReact Assisted Migration to move a Kendo UI for jQuery app to KendoReact: it scans your code, maps jQuery widgets to React components, and generates starter React code where possible. The article walks you through prerequisites, running the migration, reviewing the suggested changes, and the manual follow-ups required to reach parity (events, props, data binding, styling, unsupported features), plus how to validate and iterate safely.
Article: https://www.telerik.com/kendo-react-ui/components/migration/available-codemods
Summary: This page lists the KendoReact migration codemods and the exact changes they perform, including automated updates to imports, component names, props, event handler signatures, and subcomponent APIs across specific versions. It shows you how to run each transform with jscodeshift for JavaScript/TypeScript, what files and packages are affected, and any limitations, so you can pick the right codemod and review the diff before committing.
Article: https://www.telerik.com/kendo-react-ui/components/updates/breaking-changes/13-0-0
Summary: Before upgrading to KendoReact 13.0.0, review the documented breaking changes. The article lists component-level API removals and renames, behavior and theming updates, and other deprecations, along with required migration steps. Use it as a checklist to update imports, props, and configuration across affected packages.
Article: https://www.telerik.com/kendo-react-ui/components/updates/rendering-changes/13-0-0
Summary: KendoReact 13.0.0 introduces rendering changes across multiple components, updating DOM markup, CSS class names, and ARIA attributes. The article enumerates the affected components with before/after examples and migration notes so you can update custom CSS, query selectors, and automated tests that depend on the previous structure. Use it to assess breaking changes when upgrading and to verify UI, accessibility, and E2E test coverage.
Article: https://www.telerik.com/kendo-react-ui/components/knowledge-base/pdf-export-in-new-tab
Summary: Learn how to open a KendoReact PDFExport result in a new browser tab instead of triggering a download. You export the PDF to a Blob (e.g., via exportPDF), create a blob URL with URL.createObjectURL, open it with window.open or a programmatically clicked anchor, and then revoke the URL; account for popup blockers and CORS for images/fonts.
Article: https://www.telerik.com/kendo-react-ui/components/knowledge-base/grid-reduce-header-height
Summary: Learn how to reduce the KendoReact Grid header height by adjusting header cell padding and line-height. The article demonstrates two approaches: per-column customization via headerStyle/headerClassName or a custom headerCell, and a global CSS override targeting the Grid header, ensuring sorting and filtering icons remain aligned.
Article: https://www.telerik.com/kendo-react-ui/components/knowledge-base/grid-hide-columns-initially
Summary: Use component state and the KendoReact GridColumn hidden property to render a Grid with specific columns hidden initially. The article walks you through wiring the column menu to toggle visibility and keep Grid features like sorting, filtering, and resizing in sync with the controlled column state.
Article: https://www.telerik.com/kendo-react-ui/components/knowledge-base/expansion-panel-prevent-enter
Summary: Prevent the KendoReact ExpansionPanel from toggling on Enter by handling keyboard events explicitly. Add an onKeyDown handler to the header or nested inputs to detect Enter and call event.preventDefault() and event.stopPropagation(), or control the expanded state and ignore Enter in onChange; the examples preserve click/space behavior while disabling Enter-triggered expand/collapse.
Article: https://www.telerik.com/kendo-react-ui/components/knowledge-base/grid-wrapper-component-gridcolumn
Summary: Learn how to build a React wrapper around the KendoReact Grid while still defining columns with GridColumn. The article explains that GridColumn must be direct children of Grid and demonstrates a correct wrapper pattern that forwards props and children without wrapping or cloning the column components, so the Grid’s type checks can detect the columns reliably.
Article: https://www.telerik.com/blogs/working-kendoreact-window-component
Summary: Use the KendoReact Window component to implement draggable and resizable windows in React with controlled open/close state, positioning, and a customizable title bar and action buttons. The article shows how to wire up event handlers for close, move/drag, and resize, and how to manage multiple windows and dynamic content while keeping windows within viewport constraints.

Hello everyone,
Here are the highlights of the new online resources we published this week from 29 Oct 2025 to 05 Nov 2025:
Article: https://www.telerik.com/kendo-react-ui/components/ai-tools/ai-assistant
Summary: This guide shows you how to integrate the KendoReact AI Assistant with an LLM backend (OpenAI or Azure OpenAI) through a server-side proxy. You’ll configure system and user prompts, maintain conversation state, enable streaming responses, and implement tool/function calling with custom handlers, along with token, error, and safety handling. It includes code for wiring requests and responses, provider setup, and best practices for securing API keys.
Article: https://www.telerik.com/kendo-react-ui/components/ai-tools/agentic-ui-generator
Summary: Use the KendoReact Agentic UI Generator to convert natural-language requirements and optional structured inputs (for example, JSON schemas or sample data) into React code that assembles KendoReact components via an LLM-driven agent workflow. The article shows you how to install and configure the tooling and an LLM provider, invoke the generator, steer component/layout choices, iterate on the output, and export the code, with notes on customization and safety considerations.
Article: https://www.telerik.com/kendo-react-ui/components/ai-tools/ai-assistant/mcp-server
Summary: This article shows you how to integrate a Model Context Protocol (MCP) server with the KendoReact AI Assistant so your React app’s LLM can call custom tools and access resources. You’ll run or implement an MCP server that exposes JSON‑schema tools/resources, then configure the AI Assistant to connect to it and route tool invocations and results, including environment and authentication setup.
Article: https://www.telerik.com/kendo-react-ui/components/ai-tools/ai-assistant/prompt-library
Summary: Learn how to use the KendoReact AI Assistant Prompt Library to define and show reusable, parameterized prompts as suggestions in your React app. The article explains the prompt schema (id, title, text with variable placeholders and metadata), configuring variables (required flags, defaults, sources), grouping and ordering prompts, and wiring the library into the Assistant via the promptLibrary prop, with options to programmatically trigger prompts and customize rendering. It also covers passing runtime context into variables and handling events when a prompt runs.
Article: https://www.telerik.com/kendo-react-ui/components/ai-tools/ai-assistant/copilot-extension
Summary: Learn how to set up the KendoReact AI Assistant Copilot Extension to embed an AI copilot/chat experience in your React app. You’ll install and configure the extension, connect it to an OpenAI/Azure OpenAI backend via a secure server endpoint, and scaffold the Copilot UI with KendoReact components.

Hello everyone,
Here are the highlights of the new online resources we published this week from 20 Oct 2025 to 27 Oct 2025:
Article: https://www.telerik.com/blogs/boost-site-speed-speculation-rules-api-guide-prerendering-prefetching
Summary: Learn how to use the Speculation Rules API to cut navigation latency by prerendering and prefetching likely next pages. You’ll define a script type=speculationrules with prefetch/prerender rules (document vs list, where href_matches, eagerness), follow constraints such as same-origin prerender and anonymous-client-ip-when-cross-origin for cross-origin prefetch, and gate side effects with document.prerendering and the prerenderingchange event. The guide also shows how to measure impact via PerformanceNavigationTiming (activationStart) and when to choose prefetch vs prerender.
Article: https://www.telerik.com/blogs/static-extraction-css-js-efficiency-react-apps
Summary: Learn how static extraction compiles CSS-in-JS at build time so your React app ships less JavaScript, injects fewer styles at runtime, and reduces bundle size, hydration cost, and render time. The article contrasts runtime CSS-in-JS with statically extracted CSS, outlines build setup (Babel/SWC with Webpack or Vite) to extract CSS and enable effective code splitting and tree shaking, and shows how to handle dynamic styles and validate gains with bundle analyzers and browser DevTools.
