The following example shows how to create and position a ToolTip.

<Ellipse Height="25" Width="50" 
         Fill="Gray" 
         HorizontalAlignment="Left"
         ToolTipService.InitialShowDelay="1000"
         ToolTipService.ShowDuration="7000"
         ToolTipService.BetweenShowDelay="2000">
  <Ellipse.ToolTip>
    <ToolTip Placement="Right" 
             PlacementRectangle="50,0,0,0"
             HorizontalOffset="10" 
             VerticalOffset="20"
             HasDropShadow="false"
             Opened="whenToolTipOpens"
             Closed="whenToolTipCloses"
             >

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