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.

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.
