Raises the DragEnter event.
public:
void OnDragEnter(System::Windows::Forms::DragEventArgs ^ e);
public void OnDragEnter (System.Windows.Forms.DragEventArgs e);
abstract member OnDragEnter : System.Windows.Forms.DragEventArgs -> unit
Public Sub OnDragEnter (e As DragEventArgs)
Parameters
A DragEventArgs that contains the event data.
Remarks
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnDragEnter 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 Implementers
When overriding OnDragEnter(DragEventArgs) in a derived class, be sure to call the base class' OnDragEnter(DragEventArgs) method so that registered delegates receive the event.
