ListView.OnItemDrag Method

Raises the ItemDrag event.

[Visual Basic]
Protected Overridable Sub OnItemDrag( _
   ByVal e As ItemDragEventArgs _
protected virtual void OnItemDrag(
 ItemDragEventArgs e
protected: virtual void OnItemDrag(
 ItemDragEventArgs* e
protected function OnItemDrag(
   e : ItemDragEventArgs


An ItemDragEventArgs that contains the event data.


Raising an event invokes the event handler through a delegate. For more information, see Raising an Event.

The OnItemDrag 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 OnItemDrag in a derived class, be sure to call the base class's OnItemDrag method so that registered delegates receive the event.
