EventContext<T extends DataGridRow> class

Context provided to events for applying state transformations.

Contains only complex/stateful components:

  • SortDelegate: Pluggable sorting with debouncing and async operations
  • FilterDelegate: Pluggable filtering with debouncing and async operations
  • DataIndexer: Data filtering and sorting operations
