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 property is false.

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;
    }
}
Private Sub Ellipse_DragLeave(ByVal sender As System.Object, ByVal e As System.Windows.DragEventArgs)
    Dim ellipse = TryCast(sender, Ellipse)
    If ellipse IsNot Nothing Then
        ellipse.Fill = _previousFill
    End If
End Sub
