Hey @kharlaienko

There are 2 options here.

1. If you do not need row state for anything else except the Data Grid - you can skip updating it - the Data Grid will update the row anyway.

2. If you do need to keep track of the row state and it could potentially change from the outside - you will have to use the apiRef.current.updateRows method (see [data grid] Tree data expansion state is lost when data is updated in 6.0.0-beta.1 #7771 (comment) for more context).
