Thanks,

I got a response from the DevExpress people. I needed to use a special method on their controls like this:

                    LayoutItem liFirstName = editForm.FindItemOrGroupByName("liFirstName") as LayoutItem;
                    ASPxTextBox txtFirstName = (ASPxTextBox)liFirstName.GetNestedControl();
                    txtFirstName.Text = firstName;
