ToolStripItem.IDropTarget.OnDragOver(DragEventArgs) Method

Definition

Raises the DragOver event.

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

Sub OnDragOver (dragEvent As DragEventArgs) Implements IDropTarget.OnDragOver

dragEvent
DragEventArgs

A DragEventArgs that contains the event data.

Implements

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.
