On updating the dataItem of a master row using the Observable "set()", the master row will repaint itself. However it also collapses the expanded detail row. The detail row can be expanded programmatically but this is clunky: the detail row flashes briefly while it collapses then immediately re-expands The default behaviour should be to leave the row expanded.
Hi David,
The functionality is illustrated in the following KB article.
