>With a subclassed grid on a form is there any way to include some code in the grid class so that I don't have to explicitly call refresh and setfocus in my "add" and "delete" buttons?

1. Thisform.Refresh

2. BINDEVENT
You can use BINDEVENT(), but this reverse the issue:
"the grid class has to known that buttons exists"

2.1 "the solution"
BINDEVENT to the RecordSource Alias events: "CursorInsert", "CursorDelete"
But unfortunately the actions APPEND,INSERT,DELETE..
don't produce events.
It is possible to simulate them with CHECK,
but it becomes too much an onerous complication .

Use 1.
