TreeNodeEventHandler Delegate


Represents the method that will handle the TreeNodeCollapsed, TreeNodeDataBound, TreeNodeExpanded, or TreeNodePopulate event of the TreeView control.

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

public delegate void TreeNodeEventHandler(
	object sender,
	TreeNodeEventArgs e


Type: System.Object

The source of the event.

Type: System.Web.UI.WebControls.TreeNodeEventArgs

A TreeNodeEventArgs that contains the event data.

When you create a TreeNodeEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see NIB: Events and Delegates.

The following code example demonstrates how to use the TreeNodeEventHandler delegate to register an event-handling method programmatically.
