Hey Brian,

Many thanks for replying!  Unfortunately, refreshing the tree doesn't appear solve this particular problem, as the form below hopefully demonstrates.  If you pass false to SetDataSource(), all is well with the focus rectangle that's drawn; if you pass true (to use a data source), then the focus rect is missing its bottom border.  This happens whether data binding is set up at runtime or in the designer.

Please could let me know your thoughts on this?

Many thanks,

James
