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 sets the PlacementRectangle property of a Popup. The X, Y, Width, and Height properties of the PlacementRectangle are 50, 50, 50, and 100, respectively. The Popup is relative to the bounds of the PlacementRectangle property. Note that the PlacementRectangle property does not create a visible element in the application; the example creates a Rectangle with the same bounds to represent the PlacementRectangle.

<Canvas Width="200" Height="200" Background="Red">
  <Rectangle Canvas.Top="50" Canvas.Left="50" 
             Width="50" Height="100"
             Stroke="White" StrokeThickness="3"/>
  <Popup IsOpen="True" PlacementRectangle="50,50,50,100">
    <TextBlock FontSize="14" Background="Yellow"
               Width="140" TextWrapping="Wrap">
      This is a popup with a PlacementRectangle.
    </TextBlock>
  </Popup>
</Canvas>
