TreeView.OnTreeNodeCheckChanged Method
.NET Framework 3.0
Raises the TreeNodeCheckChanged event of the TreeView control.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)
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 Consuming Events.
The OnTreeNodeCheckChanged method 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 the OnTreeNodeCheckChanged in a derived class, be sure to call the OnTreeNodeCheckChanged method for the base class so that registered delegates receive the event.Community Additions
