11.2.2 - 2026-08-04

Improvements

• RadzenDropDown, RadzenListBox and RadzenDropDownDataGrid - Ctrl+A now selects all items in multiple selection when AllowSelectAll is enabled - press again to clear the selection. The shortcut is documented in the Keyboard Navigation section of each component.

Fixes

• RadzenDropDown and RadzenDropDownDataGrid - the popup no longer flickers when clicking a component with OpenOnFocus and no longer reopens when clicking outside of it. Clicking the component while its popup is open now closes it. Fixes #2640
• RadzenDataGrid - self-reference hierarchy view no longer degrades to O(n²) per enumeration - grids with tens of thousands of rows render instantly instead of taking seconds. Fixes #2637
• RadzenDataGrid - custom column filter expressions are now applied even when no other filters are active (#2639).
• RadzenSpreadsheet - opening xlsx files with shared formulas no longer fails - XlsxReader and XlsxWriter now support them. Fixes #2638
