Hi,
I've bound a TreeList to flat data. How can I determine if the TreeList has determined that a given row can be expanded/collapsed based upon the flat data, (i.e., how can I determine whether or not an expend/collapse arrow has been placed on the row)? This has an additional complexity in that the list cannot expand/collapse a row if it does not have children.
A use case for this would be to react to a double-click in a row and expand or collapse the row if the row is allowed to do that.
