>new to vfp 5.0 and having grid trouble. mine is the typical parent/child relationship. customer has many orders. customer_table has a key store_custid (made up of fields store and custid). order_table has a key store_custid but i want to sort the grid rows on store_custid_date.

You can not order the grid based on different index key which is not exactly the key for establishing the link on the the master file. Otherwise, the link losses...

I would advise you to use the DE, it is the replacement of hard coded opening of tables or whatsoever. Use DE to open tables, establish relationship, and boom... no need to use linkmaster, child order, etc.

Grid column accepts expression as well. mytable.qty*mytable.price
