i need some support writing an event handler. My use case is the following:
Authenticated Users insert records into a transaction table. Each transactions is related to an item, which is a static set and stored in a separate table. So in my event handler i need to get the item’s properties to determine the price and update/deduct the users “balance” property (with the option to cancel the insert, if the balance is too low).
I would be happy to get some hints… I wasn’t really successful to find some samples for event handlers.
