I call a function with a CustomerID and it returns a dataset of two
tables (Customers, Orders).
If the ID does not exist in Customers, it returns empty tables.
I also set a relationship on CustomerID between the tables, as well as
a constraint on CustomerID.

In code, if the tables are empty, I add a new row to the Customers
table where I set the Customer details
(the primary key 'CustomerID' will be set automatically).
Then, I add a new row to the Orders table, where I set the Order
details (the primary key 'OrderID' will be set
automatically).  In that new row, I also set the foreign key column of
CustomerID to -1, so that it will
be filled with the automatically created CustomerID.

Using Enterprise Library, I call UpdateDataSet once with the main
dataset and 'Customers' table as parameters,
then I call UpdateDataSet again with the main dataset and 'Orders'
table as parameters.
(Using appropriate stored procedures)

The first UpdateDataSet call works, it creates the Customer record and
gives it a new CustomerID.
However, when I call the second UpdateDataSet, the CustomerID value is
still -1 and I get the error:

Insert statement conflicted with Column Foreign Key constraint
'FKOrders_Customers'.
The conflict occurred in database 'main', table 'Customers', column
'UDFID'.

How can I update both tables at once so that the foreign key in Orders
gets filled with the proper value?

Thanks!!!!

the above error msg should say

Insert statement conflicted with Column Foreign Key constraint
'FKOrders_Customers'.
The conflict occurred in database 'main', table 'Customers', column
'CustomersID'.

I mistyped the column in the error msg

You posted this in another newsgroup, and somebody answered it there.
