Hello, Howard,
Thank you for sharing a possible solution with the KendoReact community, it is highly appreciated.
We can also recommend using a function that will return the detail component plus the custom props. The approach can be seen for custom cells, but the same one can be used for the details as well:

I hope this is helpful.
