The ICollectionChanged interface
The ICollectionChanged interface provides a powerful mechanism for notifying the UI about changes in a collection itself, rather than on individual items within the collection. By implementing this interface, a collection can raise events that inform the binding engine and UI elements about structural changes, such as additions, removals, or modifications to the collection itself.
While it is possible to assign an updated list of items to a property on your ViewModel and trigger the PropertyChanged event, dynamically changing a collection requires a more optimal approach. By utilizing a collection that implements the INotifyCollectionChanged interface, we can achieve more efficient rendering of the UI. Instead of needing to re-render the entire collection on the UI, the binding engine can perform updates in a more optimized manner, resulting in improved performance and responsiveness.
