<object Placement="PlacementMode" .../>
Property Value
Type: System.Windows.Controls.Primitives.PlacementModeA PlacementMode enumeration value that determines the orientation of the Popup control when the control opens, and that specifies how the control interacts with screen boundaries. The default is Bottom.
You can position a popup by setting the PlacementTarget, PlacementRectangle, Placement, HorizontalOffset, and VerticalOffsetProperty 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.
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>
