Protected Friend Overridable Sub OnColumnHeaderDragStarted (e As DragStartedEventArgs)

Parameters

e: DragStartedEventArgs

The data for the event.

Remarks

Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.

The OnColumnHeaderDragStarted 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 OnColumnHeaderDragStarted(DragStartedEventArgs) in a derived class, be sure to call the base class' OnColumnHeaderDragStarted(DragStartedEventArgs) method so that registered delegates receive the event.
