Represents the method that handles the DataColumnCollection.CollectionChanged event raised when adding elements to or removing elements from a collection.
C# Syntax:
[Serializable] public delegate void CollectionChangeEventHandler(object sender, CollectionChangeEventArgs e);
Parameters:
The declaration of your event handler must have the same parameters as the
CollectionChangeEventHandler delegate declaration.
When you create a CollectionChangeEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see the conceptual topic at MSDN: eventsdelegates.
