Raises the DragOver event.

 virtual void System.Windows.Forms.IDropTarget.OnDragOver(System::Windows::Forms::DragEventArgs ^ dragEvent) = System::Windows::Forms::IDropTarget::OnDragOver;

void IDropTarget.OnDragOver (System.Windows.Forms.DragEventArgs dragEvent);

abstract member System.Windows.Forms.IDropTarget.OnDragOver : System.Windows.Forms.DragEventArgs -> unit
override this.System.Windows.Forms.IDropTarget.OnDragOver : System.Windows.Forms.DragEventArgs -> unit

Sub OnDragOver (dragEvent As DragEventArgs) Implements IDropTarget.OnDragOver

Parameters

dragEvent: DragEventArgs

A DragEventArgs that contains the event data.

Implements

OnDragOver(DragEventArgs)

Remarks

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

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