Event Data

The CollectionItemChanged event's data class is CollectionItemEventArgs. The following properties provide information specific to this event:

Property	Description
Item	Gets the item whose changes invoked the Collection.CollectionItemChanged event.

Remarks

Items of the Collection collection must support the ICollectionItem interface. This interface declares the ICollectionItem.ItemChanged event. In classes implementing the interface, this event fires when properties of the item change their values.

When the item is added to the collection, an additional handler is added to the item’s ICollectionItem.ItemChanged event. This handler invokes the CollectionItemChanged event handler. When the item is removed from the collection, this additional handler is removed.
