Hi Scott,
Would it be useful to you if the row selection could be configured to only work through the checkboxes in the select column, and not through a row click, like we have it requested for the grid here?
At the moment, the only other solution I can suggest is hooking to the SelectedItemsChanged event and recursively adding all the required child items to the collection you get as a parameter before populating the SelectedItems of the treelist.
