API Updates

• FlexGrid
  • Added the stickyGroupHeaders property to keep the current group header visible while scrolling grouped data.
  • Added the preventCut property to control whether FlexGrid handles Ctrl+X cut behavior when autoClipboard is enabled. Default is false; when true, the grid leaves the cut event to the browser or external handlers.
• AutoComplete
  • Added the searchDuringComposition property to enable search during active IME composition.
  • Added customFilter and customHighlight to customize filtering and highlights in filtered results.
• MultiSelect MultiSelectListBox
  • Added customFilter to customize filtering.
• CollectionView
  • Added the newItemIndex property and insertAt method to control new item insertion. With paging, indexes map to the current page; without paging, to the source collection.
• BoxWhisker
  • Added the boxPlotData property and IBoxPlotData interface to render BoxWhisker series from pre-processed box plot statistics instead of recalculating from raw data.
• TreeGrid
  • Added the treeColumnIndex property to control the display position of tree hierarchy indicators, including expand/collapse buttons and indentation. By default, they appear in the first visible column.
• InputNumber
  • Added the truncate property to control handling of values exceeding decimal precision. By default, values are rounded; when truncate is true, excess decimals are removed.

Breaking Changes

• XLSX
  • Removed the default company value written during workbook export. Exported files now preserve an explicitly provided company value and otherwise leave the value empty instead of defaulting to GrapeCity, Inc..
• InputNumber
  • Unified truncation behavior for keyboard input and paste operations. When truncate is enabled, identical numeric values now produce consistent results regardless of the input source.
• Angular
  • Raised the minimum supported Angular version to 20.3.18 because Angular Wrapper zoneless support now depends on the Angular 20.3.18 packaging toolchain. Angular 20 stabilized zoneless behavior, and 20.3.18 was selected because that patch version did not carry the npm OSS vulnerabilities seen in earlier candidate package versions. As a result, versions earlier than Angular 20.3.18 are no longer supported.
