Raises the ItemDrag event.

[Visual Basic]
Overridable Protected Sub OnItemDrag( _
   ByVal e As ItemDragEventArgs _
)
 
[C#]
protected virtual void OnItemDrag( 
   ItemDragEventArgs e 
);
[C++]
protected: virtual void OnItemDrag( 
   ItemDragEventArgs* e 
);

Remarks

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.
