<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.
