Updates in 19.3.0 (October)

Features

• Added IgrChatComponent component.
• Grids
  • Introduced a new cell merging feature that allows you to configure and merge cells in a column based on same data or other custom condition, into a single cell.
  • The merging can be configured on the grid level to apply either:
    • onSort - only when the column is sorted.
    • always - always, regardless of data operations.
    • The default cellMergeMode is onSort.
    • The functionality can be modified by setting a custom mergeStrategy on the grid, in case some other merge conditions or logic is needed for a custom scenario.
    • It's possible also to set a mergeComparer on the individual columns, in case some custom handling is needed for a particular data field.
  • Added ability to pin individual columns to a specific side (start or end of the grid), so that you can now have pinning from both sides. This can be done either declaratively by setting the pinningPosition property on the column, or with the API, via optional parameter.
  • If property pinningPosition is not set on a column, the column will default to the position specified on the grid's pinning options for columns.
  • Sorting Improvements
    • Improved sorting algorithm efficiency using Schwartzian transformation. This is a technique, also known as decorate-sort-undecorate, which avoids recomputing the sort keys by temporarily associating them with the original data records.
    • Refactored sorting algorithms from recursive to iterative.
  • Groupby Improvements
    • Refactored grouping algorithm from recursive to iterative.
    • Optimized grouping operations.
