Occurs when a check box in the TreeView control changes state between posts to the server.
Assembly: System.Web (in System.Web.dll)
The 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.
Even though the event is fired on post back, changing a check box does not cause a post back.
For more information about handling events, see Consuming Events.
