Delete an occurence at initialisation

Hello,

I have my calendar events loaded from the database. In a particular situation I have the following:

1) My master event

2) the recurrence pattern

3) An event which is an occurence I need to delete from the occurences. I held it as an exception with a seperate field in the database saying that it is to be deleted.

My question is.. how am I going to delete an occurence from the UI at loading time or initialisation time (before the user actually moves the mouse.. this means, there is no use of the hitTest object).

thnks
