e.exception (multiple)

In my CreateUserWizard1_CreatedUser event, I have two SqlDataSource (SQL_1 and SQL_2) for inserts into two different tables (table_1 and table_2).  I also have an Inserted event for each SqlDataSource, with an e.exception handler in each.  I antrying to catch distinct insert errors but it looks like the e.exception in both inserted events catch any error from either inserting event.How can I distinguish which inserting event caused the error?
Thanks
