11.3.1

11.3.1 - 2026-09-03

Improvements

• DataGrid draws the focused cell during keyboard navigation and shows keyboard focus on grids without row selection (#2698).
• DataGrid filters array-valued properties on their element type, supports collection-level IsNull/IsEmpty filters without FilterProperty and null-guards Any/All item filters (#2696).
• Demos add a UI Blocks Gallery with 24 new block categories (#2695).

Fixes

• DataGrid, DropDown, ListBox and DropDownDataGrid no longer invoke application callbacks such as RowExpand, LoadChildData, RowSelect, RowEdit, Sort, Filter, Page and Change while their own asynchronous IQueryable load still holds the query provider. Pages sharing a DbContext threw "A second operation was started on this context instance" since 11.3.0. https://forum.radzen.com/t/21689
• DataGrid tints frozen cells together with the rest of the focused row on grids without row selection.
• Accordion and AutoComplete no longer throw "The ParameterView instance can no longer be read because it has expired" when Multiple or SelectedItem change at runtime. https://forum.radzen.com/t/21688
