         ToolTipService.ShowDuration="7000"
         ToolTipService.BetweenShowDelay="2000">
  <Ellipse.ToolTip>
    <ToolTip Placement="Right" 
             PlacementRectangle="50,0,0,0"
             HorizontalOffset="10" 
             VerticalOffset="20"
             HasDropShadow="false"

             Closed="whenToolTipCloses"
             >
      <BulletDecorator>
        <BulletDecorator.Bullet>
          <Ellipse Height="10" Width="20" Fill="Blue"/>
