Hi,

I think you should use properly established relations in the DataSet instead
of filters. DataGrid is capable of properly handling relations, so you can
click [+] on a parent row and see all child rows.

In your example, obviously, a relation must exist between the area and its
goals (each goal must reference a parent area).

Does this answer your question?
