I want a custom column in Document library which should geneate an event when
clicked on that column.

Is it possible to handle customs events handlers(not for the
add,delete,checkout checkin etc the standard events) for document library.It is
ok for me if we can write an event for a custom column or property in the menu
where (delete,checkout checkin etc are displayed).

Do you guys have any best sugessions.It is very urgent requirement.
