Hello,
I try remember column width if user changed column size and recover if return to page back. OnColumnResize event is fine, but if user change expand column (index 0), I am not able to recover width of column "expanded" (which is autogenerated ...) ?
Thank you Pavel

Hello,
This is expected as we return only the user created columns in the event, as otherwise this will add a new column to the collection and duplicate it.
I understand that this is a valid case which is currently not working, I can suggest the following approach. Add the custom expand/collapse column which will be part of the columns collection. As we already have the component for that cell exposed, it can be reused to save the time to write the column manually:
Then handle the expand and collapse on the onItemChange event instead of the onExpandChange event:
This is an example demonstrating this:
https://stackblitz.com/edit/react-sr6wfc-efev4q?file=app/main.js
I will also create a property to improve this approach:

<Column cell={GridHierarchyCell} // can be imported from "@progress/kendo-react-grid" width={32} resizable={true} field="myField" title=" "/>Then handle the expand and collapse on the onItemChange event instead of the onExpandChange event:
expandChange = (event) => { event.dataItem.expanded = !event.dataItem.expanded; event.dataItem.myField = event.dataItem.expanded; this.forceUpdate();}This is an example demonstrating this:
