ActivityCollection.ListChanged Event

Raised whenever a change is made to the contents of this ICollection.

Namespace:  System.Workflow.ComponentModel
Assembly:  System.Workflow.ComponentModel (in System.Workflow.ComponentModel.dll)

public event EventHandler<ActivityCollectionChangeEventArgs> ListChanged

In this context, adding or removing members raises the event. Modifying a member does not raise this event.

When you create an ActivityCollection 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 Events and Delegates.
