TreeView::OnAfterExpand Method (TreeViewEventArgs^)
.NET Framework (current version)
Raises the AfterExpand event.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Parameters
- e
-
Type:
System.Windows.Forms::TreeViewEventArgs^
A TreeViewEventArgs that contains the event data.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnAfterExpand method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors:
When overriding OnAfterExpand in a derived class, be sure to call the base class's OnAfterExpand method so that registered delegates receive the event.
