TreeView::TreeNodeExpanded Event
Occurs when a node is expanded in the TreeView control.
Assembly: System.Web (in System.Web.dll)
The TreeNodeExpanded event is raised when a node is expanded in the TreeView control. This allows you to provide an event-handling method that performs a custom routine whenever this event occurs.

If the SelectAction property for a node is set to TreeNodeSelectAction.Expand or TreeNodeSelectAction.SelectExpand, the TreeNodeExpanded event is also raised when that node is clicked in the TreeView control. |
