Subscribe to event for when invoice line item deleted ?

Hi-
I'd like to know when a user has removed a line item from an Invoice.
In that use case, we have some custom records regarding payments made against that line item that I need to adjust.
What options do I have for registering a handler or otherwise getting notified so I can execute some custom code?
Thanks!

Without knowing more, here are a couple general thoughts (that we use in conjunction sometimes):
- Tuck some lines information in the Tags area for the invoice. It can allow you to determine if a line is added/removed.
- Register for the "InvoiceChanged" notification. It will call your handler if user changes the invoice status (Sent, Quote,...).
- Use the OrderSaving event and open the prior version of the order to do a compare.
- Use the OrderSaved event and open the prior version of the order to do a compare.
- Monitor each invoice collection in a Shell package.
Example of monitoring list changes:
Code: Select all
// Pseudo-code from memory of another dev!
invoice = invoice you want to monitor.
var invoiceLines = (IBindingList)invoice.GetProperty("Lines");
invoiceLines.ListChanged += MyHandler;

Ok, thanks for the tip, and the example code for monitoring list changes.
....and it looks like the ListChangedEventArgs param offers a ListChangedType property which can be compared against the ListChangedType .ItemDeleted enum value.
Looks promising.
