display individual listView for every item in a listView -

i have form 2 listviews. when select item (parent) in left listview want display list of items (children) in right listview.

this picture might clarify mean.

is there simple coding approach achieve that?

i'd grateful ideas!

finally got working. copy items of listview 1 in dictionary, representing keys, whereas subitems (categorical entries) or values represented in form of generic lists individual contents displayed in listview 2, done listview itemselectionchanged event.
