@clayinfor everything looks good regarding expanding and collapsing but i see a related issue

1. on http://localhost:4300/ids-data-grid/tree-grid.html
2. collapse all parents (Building 4 and Building 5) so they are all collapsed
3. sort on the name column
4. notice after rerender/sort the children are reopened. (should be a rowExpanded) on the data it reads in the formatter. So should respect sorting.
