Pull request overview
This PR optimizes the PivotGrid widget by creating the FieldChooserBase component only once during the initial render, then updating its options on subsequent renders instead of recreating it each time. This reduces overhead and prevents accumulation of duplicate event listeners.
Changes:
- Modified
_renderContentImplto conditionally create FieldChooserBase on first drawing or update options on subsequent renders - Added a test verifying that FieldChooserBase maintains a single instance and doesn't accumulate event listeners when the dataSource is reassigned
