Hi,
I want to open a Paradox Table with a TTable/TDatasource pair but I want to 
show some records (filtered or ranged) on one TDBstringGrid and other 
(different filter/range) on other TDBstringGrid at the same time. I also 
want these TDBstringGrids  to scroll independently
How can I do this ?

thanks in advance

By using two TTables. One TTable = one cursor. There is no
TDBStringGrid. I assume you mean TDBGrid.

You do not duplicate the fields. You use two TTables that both open the
same database table and access the same fields in the database table.
You are just opening two cursors on the same table and fields.

thanks Bill,
this approach I use but I want something to avoid duplicating the fields 
using two tables, but now I realize that isn't possible to apply two 
concurrent filters to the same table  or use the same fields.

You could always use a TClientDataset instead of a TTable, and then use a 
CloneCursor to have 2 different CDS's pointing to the same data in memory.
