Occurs when an object is dragged out of the bounds of an element that is acting as a drop target without being dropped.
(in PresentationCore.dll)XMLNS for XAML:
See AddDragLeaveHandler, RemoveDragLeaveHandler
<object DragDrop.DragLeave="DragEventHandler" .../>
This event is raised once each time an object is dragged out of the bounds of an element that is acting as a drop target without being dropped. This event is not raised if the element’s AllowDrop property is false.
You typically handle this event to undo any changes that you made in the DragEnter event handler.
Routed Event Information
The following example shows the DragLeave event handler for an Ellipse element. This code undoes the preview performed in the DragEnter event handler by applying the saved Brush to the ellipse.
private void ellipse_DragLeave(object sender, DragEventArgs e)
Ellipse ellipse = sender as Ellipse;
if (ellipse != null)
ellipse.Fill = _previousFill;
