Examples

The following example creates four Popup controls that are relative to an image. Each Popup has a different value for the placement property.

<Canvas Width="200" Height="150">
  <Image Name="image1"
         Canvas.Left="75" 
         Source="Water_lilies.jpg" Height="200" Width="200"/>
  <Popup IsOpen="True" PlacementTarget="{Binding ElementName=image1}"
         Placement="Bottom">
    <TextBlock FontSize="14" Background="LightGreen">Placement=Bottom</TextBlock>

  </Popup>
  <Popup IsOpen="True" PlacementTarget="{Binding ElementName=image1}"
         Placement="Top">
    <TextBlock FontSize="14" Background="LightGreen">Placement=Top</TextBlock>

  </Popup>
  <Popup IsOpen="True" PlacementTarget="{Binding ElementName=image1}"
         Placement="Left">
    <TextBlock FontSize="14" Background="LightGreen">Placement=Left</TextBlock>

  </Popup>
  <Popup IsOpen="True" PlacementTarget="{Binding ElementName=image1}"
         Placement="Right">
    <TextBlock FontSize="14" Background="LightGreen">Placement=Right</TextBlock>

  </Popup>
</Canvas>

Remarks

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

If the MenuDropAlignment property is true, setting Placement to Left or Right reverses the position of the Popup; a Popup with Placement set to Left aligns its left edge with the right edge of PlacementTarget and a Popup with Placement set to Right aligns its right edge with the left edge of PlacementTarget.
