ItemUpdating or ItemUpdated ?

Madhur Ahuja

Hello

I have to write an event handler, which will change the values of items corresponding to the old value of the item in the list to the new value. Thus, while writing the event handler, I have to search for the items in other list having old value and then change them to the new value.

Which type of event handler should I go for

I guess, I cannot get the old value in the ItemUpdated event, since the event has already been committed.
While, in the ItemUpdating, user can cancel the event.

Any ideas

Thanks,
Madhur

Hi

But in ItemUpdating, the event handler will run even if the user cancels the updation.
Isnt it

ItemUpdating should run

- after the form is submitted

- before the value is written to DB

right

Oh, I thought, its run just when the user clicks Edit. Ill try that, thanks

You should take a look at this Month's MSDN Magazine article on MOSS Event Handlers... it explains quite well how and when to use each event handler type.
