Leadtools.Annotations.Automation Assembly > Leadtools.Annotations.Automation Namespace > AnnAutomation Class : OnDragDrop Method |
protected virtual void OnDragDrop( AnnDragDropEventArgs e )
'Declaration
Protected Overridable Sub OnDragDrop( _ ByVal e As AnnDragDropEventArgs _ )
protected virtual void OnDragDrop( AnnDragDropEventArgs e )

function Leadtools.Annotations.Automation.AnnAutomation.OnDragDrop( e )
Raising an event invokes the event handler through a delegate. The OnDragDrop 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 OnDragDrop in a derived class, be sure to call the base class's OnDragDrop method so that registered delegates receive the event.
