Rendering Changes in 9.0.0

Updated on Nov 12, 2025

DateTimePicker

• The div.k-calendar-container element in the popup renders a k-datetime-container class instead.
• The order of the Set and Cancel buttons in the adaptive popup (button.k-time-accept and button.k-time-cancel) is reversed, so that Set is on the left.
• The ButtonGroup in the popup renders a k-button-group-solid CSS class.

Gantt

• The task delete button (.k-task-delete) renders as an a element instead of span.

Gantt, Grid, TreeList

The k-alt CSS class on alternating (even) table rows is removed. Use k-table-alt-row instead.

Grid, TreeList

• The chips in the group panel (span.k-chip-content) render an additional span.k-chip-label that wraps the text label.
• The table.k-grid-table element is a direct child of div.k-grid-content when virtual scrolling is not used.
• The column menu opener (.k-grid-column-menu) in the header cells renders as an a element instead of span.
• The header cell in the drag column no longer renders a k-drag-cell CSS class.

ToggleButton

The span.k-button-icontext element is not rendered if the Button displays only an icon.
