11.1.0

11.1.0 - 2026-07-02

Improvements

• RadzenPanelMenu RenderMode — new RenderMode property (Client by default, Server) that renders a collapsed item's children only while it is expanded, keeping the DOM small and keyboard navigation fast for large navigation menus.
• RadzenDataGrid AllowSortingColumnPicker — sort the columns listed in the column picker.
• RadzenSpreadsheet accessibility — screen-reader and keyboard support: active cell on entry, F6 region cycling, a grid tab stop, and a filterable keyboard-shortcuts dialog. Also adds a two-way bindable SelectedSheetIndex.
• Comprehensive keyboard and screen-reader accessibility (W3C ARIA APG) across composite components — Menu, ContextMenu, PanelMenu, ProfileMenu, Tabs, Tree, SelectBar, Pager, RadioButtonList, Steps, DropDown, DropDownDataGrid, SplitButton, Splitter and more now use a single tab stop with aria-activedescendant, full Arrow / Home / End / Enter / Space / Escape handling, and type-ahead where applicable.
• RadzenSplitButton: Space/Enter trigger the main action; Arrow and Alt+Arrow open the menu.
• RadzenAccordion: improved keyboard focus handling and accessibility.
• RadzenSwitch: keyboard focus now shows a focus outline.
• RadzenTree: the focused node scrolls into view during keyboard navigation.
• RadzenCarousel / RadzenSidebar: hidden or inactive content is no longer focusable.
• Unified focus-state colors and styles across form components and buttons.
• Updated the keyboard-navigation documentation across the component demos.

Fixes

• RadzenFormField: fixed the label association — removed an invalid for on the wrapper element and the empty for that made the label appear unassociated.
• RadzenChart: the tooltip no longer disappears when the pointer moves over it.
• RadzenMenu: opening a submenu now closes sibling submenus so two submenus are no longer open at once; improved overall close behavior.
• RadzenDropDownDataGrid: the grid no longer exposes a stale aria-activedescendant when no row is active.
• RadzenDropDown: tabbing out of an open (non-searchable) dropdown no longer skips the next element.
• RadzenSplitter: keyboard resize fixed; dragging the last pane past its Max no longer snaps it shut.
• RadzenMask / RadzenTextBox / RadzenTextArea / RadzenPassword / RadzenAutoComplete: keep the DOM input in sync with the bound value on .NET 10.
• RadzenHtmlEditor: fixed a null reference in table context building.
• RadzenDataGrid: the advanced filter popup no longer closes on touch devices when the on-screen keyboard opens, and the SimpleWithMenu date filter calendar no longer opens then immediately closes.
• RadzenPanelMenu: consistent alignment between parent and child items in the navigation rail layout.
• RadzenScheduler: an AppointmentRender CSS class no longer overrides the default event content styling.
