Called before the DragOver event occurs.
Assembly: System.Windows (in System.Windows.dll)
'Declaration Protected Overridable Sub OnDragOver ( _ e As DragEventArgs _ )
protected virtual void OnDragOver( DragEventArgs e )
The OnDragOver method is called before any event handler for the DragOver event is called. This method allows derived classes to handle the DragOver event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnDragOver in a derived class, be sure to call the base class’s OnDragOver method so that registered delegates receive the event.
