Dear Glenn,
I am not understand the method you told me. Do you have any sample code for reference?
I would like to describe more details about what i am try to do. Let's me give a sample.
1)I have a main form that for display and key in Invoice details. A grid is keep record of the Invoice sales items record. Each items records have unique Invoice number.
2) after key in all the sales items record of the Invoice, the records will save into Invoice Table which they will have same invoice number(primary key)
3) i will have another form(to search out the particular invoice details) which have a grid and have records sort by the invoice number.
4) if chose the particular invoice number, i wish to pass the parameter to the main form for display the chosed invoice sales items records on the main form grid.
5) in that way, i can modify the records or delete the records or whole invoice record.

Do you think that is posible to do it with the way you told me ? and how ?thanks
