I'm doing a requery of an EnhancedList after making some updates to the BO that I have bound to it.  After the requery the focus always jumps to the top of the list.  Is there a way to keep it from doing this and have the focus make sense.  i.e. Focus on a newly added row, focus on the next if one is deleted, and keep current focus on an edit?

Well, store off the PK of the row.  When you setup the PopulationDataSourceSettings, you can provide the field that will be stored in the Tag property of each row.  Get the PK value and then iterate through the rows when repopulated and set the item that has a matching PK.
