v1.5.1

Stable Release · October 14, 2026 · NuGet · GitHub Release

WinUI.TableView v1.5.1 is a maintenance release focused on improving stability, layout consistency, column resizing, and performance across WinUI and Uno Platform. This update also introduces Polish localization and improvements to the sample application and automated testing infrastructure.

🐛 Fixes

  • Fixed an issue where scrolling with frozen columns could produce a negative-width header clipping rectangle, causing an exception on WinUI or disappearing column headers on Uno Platform by @SolidRockProgrammer in #438.
  • Fixed column resizing in Preview mode, where double-clicking a column divider to auto-size could cause misaligned cell content, incorrect selection borders, or unexpected visual offsets by @w-ahmad in #447.
  • Fixed alternating row colors becoming inconsistent after scrolling, recycling rows, or modifying the items collection by @w-ahmad in #451.
  • Fixed column resizing unexpectedly scrolling the table horizontally, particularly after editing a cell. Row size changes now preserve horizontal scroll position, while row details expansion continues to bring the affected row into view when appropriate by @w-ahmad in #455.
  • Fixed row details visibility on Uno Platform when a row's selection state changes in VisibleWhenSelected mode by @w-ahmad in bb90f6b.
  • Fixed incorrect column header alignment and clipped selection checkboxes when TableView is displayed with an empty ItemsSource. Header offsets and scrollbar margins are now updated correctly when the collection or header configuration changes by @w-ahmad in #459.

Enhancements

  • Added Polish (pl-PL) localization, providing translations for the control's existing resource strings by @bartazalbln in #446.
  • Reduced redundant object allocations by reusing common bindings and brushes across cells, rows, and headers. Shared resources are maintained per UI thread to preserve thread affinity by @w-ahmad in #448.

🧪 Testing and Maintenance

  • Made the main WinUI sample application compatible with Native AOT and trimming, removing the need for the separate AotTestApp project by @w-ahmad in #450.
  • Fixed the CI workflow to ensure automated tests are actually executed and test failures are correctly reported by @w-ahmad in #452.
  • Expanded cross-platform test coverage by sharing existing WinUI test sources with Uno Platform test projects and running independent platform test suites in CI by @w-ahmad in #460.
  • Migrated WinUI tests to an unpackaged MSTest runner using Microsoft.Testing.Platform, removing MSIX deployment requirements and enabling direct execution through dotnet test by @w-ahmad in #462.
  • Improved sample application development and packaging workflows, including unpackaged debugging and a dedicated script for generating Microsoft Store upload packages.

Documentation

  • Corrected the conditional styling documentation to clarify that styles are evaluated in order, the first matching style wins, and column-level styles take precedence over TableView-level styles by @w-ahmad in #453.
