Article: https://www.telerik.com/kendo-jquery-ui/documentation/knowledge-base/show-week-number-scheduler-timeline-month-views
Summary: This article shows how to display week numbers in the Kendo UI for jQuery Scheduler Timeline and Month views by customizing the rendered header in the dataBound/navigate events. It computes ISO (or culture-specific) week numbers for the visible dates using kendo.date utilities and injects them into the DOM so the week labels stay in sync as the user navigates or resizes.

24 Nov to 01 Dec 2025: highlights of the new online resources that we published last week.
Article: https://www.telerik.com/kendo-jquery-ui/documentation/knowledge-base/compact-number-formatting
Summary: Learn how to format numbers in compact notation (K, M, B) in Kendo UI for jQuery using Intl.NumberFormat with notation: "compact" and a reusable formatter function. The article shows how to integrate the formatter into Grid column templates, Chart labels, and other widget templates with culture-aware output and precision control, and notes browser support considerations. Use it to keep numeric displays concise without changing the underlying data.
Article: https://www.telerik.com/kendo-jquery-ui/documentation/knowledge-base/automatic-scrolling-taskboard-drag-drop
Summary: Learn how to add automatic scrolling to the Kendo UI jQuery TaskBoard during card drag-and-drop. You detect the pointer near the column or TaskBoard container edges and programmatically adjust scrollTop/scrollLeft (e.g., via a timer or requestAnimationFrame) while the drag is active to enable vertical and horizontal scrolling. The article wires this logic into the TaskBoard’s drag/sort events so you can reliably move cards to off-screen targets across long columns.

10 Nov to 17 Nov 2025: highlights of the new online resources that we published last week.
Article: https://www.telerik.com/kendo-jquery-ui/documentation/ai-components
Summary: Integrate Kendo UI for jQuery AI components—AI Prompt and AI Chat—with LLM providers (OpenAI, Azure OpenAI, custom endpoints) through a backend proxy. The article explains configuration and event handling (prompt templates, system messages, streaming responses, conversation history, request/response/error events) and covers API key security to implement AI chat and prompt workflows in your app.
Article: https://www.telerik.com/kendo-jquery-ui/documentation/knowledge-base/kendo-ui-clear-icon-span
Summary: This article explains how Kendo UI for jQuery renders the clear (x) icon as a span inside input widgets and how to reliably target it. You will learn how to enable or disable the clear button and use CSS/JavaScript to hide, style, or reposition the generated icon span to avoid overlap or alignment issues in TextBox, ComboBox, DropDownList, and DatePicker widgets.
Article: https://www.telerik.com/kendo-jquery-ui/documentation/controls/sortable/accessibility/overview
Summary: This article outlines the accessibility behavior of the Kendo UI for jQuery Sortable, covering WCAG 2.2/Section 508 targets, WAI-ARIA semantics, focus management, and screen reader considerations. It clarifies keyboard interaction and known limitations of drag-and-drop, and guides you on structuring markup and configuration to achieve an accessible sorting experience.
Article: https://www.telerik.com/kendo-jquery-ui/documentation/controls/dropdowntree/binding/load-on-demand
Summary: Configure the Kendo UI for jQuery DropDownTree to load child nodes on demand (lazy loading) from a remote endpoint when a node is expanded. Set loadOnDemand: true and bind a HierarchicalDataSource with transport.read, schema.model.id, and schema.model.hasChildren; pass the expanded node’s id to the server so it returns only that node’s children, reducing the initial payload for large hierarchies.
Article: https://www.telerik.com/kendo-jquery-ui/documentation/controls/sortable/accessibility/keyboard-navigation
Summary: This article documents keyboard navigation and accessibility for the Kendo UI for jQuery Sortable, showing how you focus the component, move between items, initiate reordering via keyboard, reposition items, drop, and cancel. It specifies the supported keyboard shortcuts plus the ARIA roles/attributes and focus management used to meet WCAG requirements and support screen readers, so you can implement and test accessible item reordering.
Article: https://www.telerik.com/kendo-jquery-ui/documentation/knowledge-base/fixing-bar-visibility-chart-long-labels
Summary: When long category axis labels in a Kendo UI for jQuery Bar/Column Chart consume too much space, the plot area can collapse and bars may appear hidden. Fix this by using categoryAxis.labels.visual to render wrapped or truncated labels within a fixed width and adjusting axis padding/margins, so the chart reserves bounded space for labels. The article includes sample code to measure text and draw multi-line labels, preserving bar visibility and label readability.
Article: https://www.telerik.com/kendo-jquery-ui/documentation/knowledge-base/stop-event-propagation-buttons-panelbar-header-contenturl
Summary: Learn how to prevent Kendo UI for jQuery PanelBar headers from expanding/selecting when clicking buttons placed in the header while using contentUrl. The article shows binding delegated handlers and calling e.preventDefault() and e.stopPropagation() on button click (and mousedown/touchstart if needed) so the event doesn’t bubble to the header anchor (.k-link), keeping header controls interactive without triggering PanelBar actions.
Article: https://www.telerik.com/kendo-jquery-ui/documentation/knowledge-base/preventing-auto-increment-dragging-kendo-ui-jquery-spreadsheet
Summary: Learn how to prevent auto-increment when dragging the fill handle in the Kendo UI for jQuery Spreadsheet by forcing drag-fill to copy the original value instead of creating a numeric/date series. You’ll intercept the Spreadsheet change event to detect drag-fill and programmatically reset the target range, with an option to hide the fill handle via CSS if you need to disable drag filling entirely.

The article shows the exact classes to target (e.g., .k-rating-item, .k-selected, .k-hover, .k-icon/.k-svg-icon) with sample rules.
