Details
The IsEqual event is fired whenever the collection needs to determine if two components are equal.
This is typically handled automatically when performing actions that require searching such as Remove or testing for duplicates. The event allows you to determine whether the object being tested is the object being searched for.
This feature is provide for completeness and is unlikely to be required for most development purposes.
Example
The source and object parameters contain the two instances to compare.
Here the name property of the two "Customer" objects is being tested.
