TreeView.OnTreeNodeCheckChanged Method (TreeNodeEventArgs)
Assembly: System.Web (in System.Web.dll)
The TreeNodeCheckChanged event is raised when a check box in the TreeView control changes state between posts to the server. This allows you to provide an event-handling method that performs a custom routine, such as updating a database or the displayed content, whenever this event occurs.
Raising an event invokes the event handler through a delegate. For more information, see NIB: Consuming Events.
Themethod also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors:
When overriding thein a derived class, be sure to call the method for the base class so that registered delegates receive the event.
