11.3.2

11.3.2 - 2026-09-04

Improvements

• DataGrid auto-scrolls horizontally while a column header is dragged near either edge of the scroll container, so a column can be dropped onto a destination outside the visible area in one drag, in LTR and RTL (#2690).
• Demos link every component page to a markdown twin of its API reference.

Fixes

• DataGrid, DataList, PivotDataGrid, DropDown, ListBox and DropDownDataGrid execute bound IQueryable data synchronously again, as in 11.2.8 and earlier. The asynchronous execution introduced in 11.3.0 released the renderer while a query still held the DbContext, so any other component on the page that enumerated a query from the same context during render, such as a DropDown in a FilterTemplate, threw "There is already an open DataReader associated with this Connection" or "A second operation was started on this context instance". Applications that need asynchronous execution use LoadData.
• DataGrid reports zero items instead of one for an empty virtualized data source (#2691).
• DataGrid no longer leaks document mouse listeners when a column drag starts again before the previous one ended, and a quick click on Blazor Server no longer leaves a ghost header following the pointer until the next mouseup.
• Tooltip measures the popup with the resolved side's arrow class before placing it, so a Bottom tooltip that falls back to Top no longer ends inside its target and flickers near the bottom of the viewport. https://forum.radzen.com/t/21690
