DetailsList control: How to deselect rows after disableSelectionZone is set to true?

[T41WO]

The requirement is to disable further selection after N number of rows is selected. This is achieved by using selection.count.

However, user should be able to "deselect" an already selected row to achieve N - 1 rows selected (setting disableSelectionZone back to false), in other to perhaps select another.

How is this achievable?

Thanks

Rather than using disableSelectionZone, maybe you could try passing in a custom Selection object (via the selection prop) with an override of canSelectItem, which returns false if too many items are selected.
