How do I create a unique unbound DataGridViewColumn?

[wannabe geek]

I need a tutorial on how to create an unbound column for a datagridview.
everything is unbound and programmatically populated.
is CellValidating the appropriate place to enforce non-duplication? how to
enforce it?

Oh, now I see i will need numerous columns combined into one "key". one text
column and three number columns.
