elegant and resource free (at server side too). In my application
there is a table with tree-organized dictionary data. In another
tables these data is using to fill some fields, so in case of
using separate datasets I need to create one dataset for each sub-tree.
At now I found only one way to use one dataset for the tree-organized
dictionary (without reopening dataset) - I use Filtered=True (without
setting Filter property), then I provide onFilterRecord event code. When
I need to view another sub-tree, I call IB_Query.RefreshKeys and in the
onFilterRecord handler manually select needed records.
