TreeView::TreeNodeCollapsed Event

 

Occurs when a node is collapsed in the TreeView control.

Namespace:   System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public:
event TreeNodeEventHandler^ TreeNodeCollapsed {
	void add(TreeNodeEventHandler^ value);
	void remove(TreeNodeEventHandler^ value);
}

The TreeNodeCollapsed event is raised when a node is collapsed in the TreeView control. This allows you to provide an event-handling method that performs a custom routine whenever this event occurs.

For more information about handling events, see NIB: Consuming Events.

The following code example demonstrates how to use the TreeNodeCollapsed event to update the content of a Label control when the user collapses a node in the TreeView control.
