TreeView.TreeNodeCheckChanged Event
.NET Framework 3.0
Occurs when a check box in the TreeView control changes state between posts to the server.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)
Assembly: System.Web (in system.web.dll)
public: event TreeNodeEventHandler^ TreeNodeCheckChanged { void add (TreeNodeEventHandler^ value); void remove (TreeNodeEventHandler^ value); }
/** @event */ public void add_TreeNodeCheckChanged (TreeNodeEventHandler value) /** @event */ public void remove_TreeNodeCheckChanged (TreeNodeEventHandler value)
In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.
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.
Even though the TreeNodeCheckChanged event is fired on post back, changing a check box does not cause a post back.
