11.2.6 - 2026-08-20

Improvements

• RadzenDataGrid, RadzenDataFilter and RadzenPivotDataGrid In and NotIn filter operators now filter scalar properties, including nullable value types - previously such filters were silently ignored. Filter values are normalized to the property type, so int[], List<long?> or List<object> values filter a long? property correctly, null or scalar filter values are ignored instead of throwing, and the generated expression translates to SQL with Entity Framework Core. SecondFilterOperator now also supports In and NotIn. Fixes #2663 (thanks @simonluebker)

Fixes

• RadzenDataGrid no longer triggers the critical aria-required-children axe violation - the grid role moved to the scrollable data element so it owns only row structure, keyboard navigation and focus behavior are preserved. Fixes #2669
• Localization - application resx overrides for Radzen strings are now resolved as documented. Overrides embedded as Radzen.Blazor.RadzenStrings.[culture].resources in the application are consulted before the built-in translations, with fallback to the bundled strings for missing keys. Fixes #2668
• RadzenRangeNavigator handle labels now respect the date FormatString while dragging, including month names, two-digit years, 12-hour clock with AM/PM and quoted literals (#2666, thanks @wimsoetens-cmd)
