Occurs when a check box in the System.Web.UI.WebControls.TreeView control changes state between posts to the server.
The TreeView.TreeNodeCheckChanged event is raised when a check box in the System.Web.UI.WebControls.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 TreeView.TreeNodeCheckChanged event is fired on post back, changing a check box does not cause a post back.
