TreeViewEventHandler Delegate

Represents the method that will handle the AfterCheck, AfterCollapse, AfterExpand, or AfterSelect event of a TreeView.

[Visual Basic]
Public Delegate Sub TreeViewEventHandler( _
   ByVal sender As Object, _
   ByVal e As TreeViewEventArgs _
public delegate void TreeViewEventHandler(
   object sender,
   TreeViewEventArgs e
public __gc __delegate void TreeViewEventHandler(
   Object* sender,
   TreeViewEventArgs* e

[JScript] In JScript, you can use the delegates in the .NET Framework, but you cannot define your own.

Parameters [Visual Basic, C#, C++]

The declaration of your event handler must have the same parameters as the TreeViewEventHandler delegate declaration.

The source of the event.
A TreeViewEventArgs that contains the event data.


When you create a TreeViewEventArgs 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 Events and Delegates.
