You can position a popup by setting the PlacementTarget, PlacementRectangle, Placement, HorizontalOffset, and VerticalOffsetProperty properties. For more information, see Popup Placement Behavior.

The following example creates a Popup that is the child of a Canvas, and sets PlacementTarget to ellipse1, so the popup is relative to the Ellipse.

<Canvas Margin="5" Background="Red" Width="200" Height="150" >

  <Ellipse Name="ellipse1"
           Canvas.Top="60" Canvas.Left="50"
           Height="85" Width="60" 
           Fill="Black"/>

  <Popup IsOpen="True" PlacementTarget="{Binding ElementName=ellipse1}">
    <TextBlock Background="LightBlue" FontSize="18">This is a Popup</TextBlock>
  </Popup>
</Canvas>
