System.Web.UI.WebControls Namespace TreeView Class
.NET Framework version 2.0
Occurs when a node is collapsed in a TreeView control.
[ VB ]
Public Event TreeNodeCollapsed As TreeNodeEventHandler
[ C# ]
public event TreeNodeEventHandler TreeNodeCollapsed;
[ C++ ]
public: __event TreeNodeEventHandler* TreeNodeCollapsed;
In [ JScript ], you can handle the events defined by a class, but you cannot define your own.
The TreeNodeCollapsed event is raised whenever a node in a TreeView control is collapsed.
This allows you to provide an event-handling method that performs a custom routine, such as change the image for a node, whenever this event occurs.
The method assigned to handle the event is passed an argument of type TreeNodeEventArgs object containing data related to this event. The following TreeNodeEventArgs properties provide information specific to this event.
