Slava,

>I replaced dvOrdersByEmployeeID with the DefaultView in the CustomerOrdersForm.cs (16 occurences). BindingSource is Orders, BindingSourceMember is Orders.DefaultView. To make sure that I did not change anything else I reinstalled the MM Framework today. I got the same result.

Hmmm...here's something to try. In the MM .NET sample application can you set the CustomerOrdersForm buttons BindingSourceMember to:

Orders.DefaultView

Let me know if you get an error at run time.

Regards,
