It uses the SampleCRMApplication example to reproduce the problem.I intend that lstCard sorts the registers for the column to cc_CardNumber.
Then, I modified the "Private Sub EditCreditCard()" including CustomerCreditCards.Sort = "cc_CardNumber" after lstCards.Requery()
When you edit or include a register from the CreditCardEditor form the lines of lstCards you start to present given incorrect, demonstrating that, of some form, sort affected the routine. Remembering, an option luck is important.
It includes some registers and later it edits the line to understand the problem better.
It forgives me if the translation of the Alta Vista is not if making to understand.
