I'm looking to use a List object for storing integers, but unlike the datatable, it doesn't raise any event such as ItemAdd, ItemRemoved, ItemChanged which I need to be notified of.
The list is to contain the ids of the rows that must be hidden from the user in an inherited DataView. I would simply listen on the SomethingChanged event and refresh the filter string to match (no fine grained control over this unless it is necessary for performance).
I could inherit the a List object with my own implementation or hide the List's reference in my object and implement my own add/remove methods in the inherited DataView.
The first one forces me to override/shadow every overload of every method for adding, removing, setting any value and make sure none of these call the other or the event would be fired twice. Quite a mess.
And the second leads me to implementing add, add many, remove, remove many, set, replace, etc. methods in my inherited DataView which leads to a lot of unnecessary methods and complexity.
I was wondering if there were any premade (either built-in or freely available on the web) collection (generic as possible) that would throw these events for me and allow me to just add that single event handler...
