TreeView.TreeNodeExpanded Event
.NET Framework 3.0
Occurs when a node is expanded in the TreeView control.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)
Assembly: System.Web (in system.web.dll)
public: event TreeNodeEventHandler^ TreeNodeExpanded { void add (TreeNodeEventHandler^ value); void remove (TreeNodeEventHandler^ value); }
/** @event */ public void add_TreeNodeExpanded (TreeNodeEventHandler value) /** @event */ public void remove_TreeNodeExpanded (TreeNodeEventHandler value)
In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.
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.
Note: |
|---|
| 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. |
