Examples

This example shows a simple Popup with content defined inline.

<Grid x:Name="Output" HorizontalAlignment="Left" VerticalAlignment="Top" Grid.Row="1">
    <StackPanel>
        <Button Content="Show Popup (using Offset)" Click="ShowPopupOffsetClicked"/>
    </StackPanel>
    <Popup VerticalOffset="10" HorizontalOffset="200" x:Name="StandardPopup">
        <Border BorderBrush="{StaticResource ApplicationForegroundThemeBrush}" 
                Background="{StaticResource ApplicationPageBackgroundThemeBrush}"
                BorderThickness="2" Width="200" Height="200">
            <StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
                <TextBlock Text="Simple Popup" FontSize="24.667" HorizontalAlignment="Center"/>
                <Button Content="Close" Click="ClosePopupClicked" HorizontalAlignment="Center"/>
            </StackPanel>
        </Border>
    </Popup>
</Grid>

// Handles the Click event on the Button inside the Popup control and 
// closes the Popup. 
private void ClosePopupClicked(object sender, RoutedEventArgs e)
{
    // if the Popup is open, then close it 
    if (StandardPopup.IsOpen) { StandardPopup.IsOpen = false; }
}

// Handles the Click event on the Button on the page and opens the Popup. 
private void ShowPopupOffsetClicked(object sender, RoutedEventArgs e)
{
    // open the Popup if it isn't open already 
    if (!StandardPopup.IsOpen) { StandardPopup.IsOpen = true; }
}

This example shows a Popup that has a UserControl set as its Child element. The UserControl defines the content of the Popup.

<Popup x:Name="ParentedPopup" HorizontalOffset="200" VerticalOffset="200">
    <local:PopupInputContent/>
</Popup>

<UserControl

        {
            // in this example we assume the parent of the UserControl is a Popup 
            Popup p = this.Parent as Popup;

            // close the Popup
            if (p != null) { p.IsOpen = false; }  
        } 
    }
}

Remarks

Do not use a Popup if a Flyout, MenuFlyout, ToolTip, or ContentDialog is more appropriate.

Popup is a general purpose container for hosting UIElements on top of existing content. You typically use a Popup to temporarily display content that accomplishes a particular task. The Popup does not have a default visual template. Instead, you must set the content yourself by specifying a single Child element as content. You can define the Popup content inline, but it's common to define the content as a UserControl, and then set the UserControl as the Child of the Popup.

You position the Popup by setting the HorizontalOffset and VerticalOffset properties. The Popup is offset relative to its immediate parent container. A Popup is not modal, so input to the screen behind it is not blocked.

To show a Popup, set its IsOpen property to true. To hide the Popup, set IsOpen to false. You can set IsLightDismissEnabled to make the Popup hide automatically when a user taps anywhere away from it.

The Popup can host input controls. When hosting input controls like TextBox, the touch keyboard might slide into view when the user touches the input control. If the Popup's parent container is already in the visual tree, the Popup automatically repositions itself when the touch keyboard is in view. Otherwise, the Popup is not repositioned and the touch keyboard can cover it. This can happen if you create the Popup in code and set IsOpen to true without adding the Popup as a child of an element in the visual tree.

The Popup doesn't fire RoutedEvents, for example KeyDown and PointerPressed. You can wire an event handler for these RoutedEvents on the child of the Popup.

Note

When used with XAML Islands (DesktopWindowXamlSource): By default, this control is automatically constrained within the work area of its display. To change this behavior, set the DesktopWindowXamlSource.ShouldConstrainPopupsToWorkArea property of the XAML island that contains this control.

KeyDown	Occurs when a keyboard key is pressed while the UIElement has focus. (Inherited from UIElement)
KeyUp	Occurs when a keyboard key is released while the UIElement has focus. (Inherited from UIElement)
LayoutUpdated	Occurs when the layout of the visual tree changes, due to layout-relevant properties changing value or some other action that refreshes the layout. (Inherited from FrameworkElement)
Loaded	Occurs when a FrameworkElement has been constructed and added to the object tree, and is ready for interaction. (Inherited from FrameworkElement)
Loading	Occurs when a FrameworkElement begins to load. (Inherited from FrameworkElement)
LosingFocus	Occurs before a UIElement loses focus. This event is raised synchronously to ensure focus isn't moved while the event is bubbling. (Inherited from UIElement)
LostFocus	Occurs when a UIElement loses focus. This event is raised asynchronously, so focus can move again before bubbling is complete. (Inherited from UIElement)
ManipulationCompleted	Occurs when a manipulation on the UIElement is complete. (Inherited from UIElement)
ManipulationDelta	Occurs when the input device changes position during a manipulation. (Inherited from UIElement)
ManipulationInertiaStarting	Occurs when the input device loses contact with the UIElement object during a manipulation and inertia begins. (Inherited from UIElement)
ManipulationStarted	Occurs when an input device begins a manipulation on the UIElement. (Inherited from UIElement)
ManipulationStarting	Occurs when the manipulation processor is first created. (Inherited from UIElement)
NoFocusCandidateFound	Occurs when a user attempts to move focus (via tab or directional arrows), but focus doesn't move because no focus candidate is found in the direction of movement. (Inherited from UIElement)
Opened	Fires when the IsOpen property is set to true.
PointerCanceled	Occurs when a pointer that made contact abnormally loses contact. (Inherited from UIElement)
PointerCaptureLost	Occurs when pointer capture previously held by this element moves to another element or elsewhere. (Inherited from UIElement)
PointerEntered	Occurs when a pointer enters the hit test area of this element. (Inherited from UIElement)
PointerExited	Occurs when a pointer leaves the hit test area of this element. (Inherited from UIElement)
PointerMoved	Occurs when a pointer moves while the pointer remains within the hit test area of this element. (Inherited from UIElement)
PointerPressed	Occurs when the pointer device initiates a Press action within this element. (Inherited from UIElement)
PointerReleased	Occurs when the pointer device that previously initiated a Press action is released, while within this element. Note that the end of a Press action is not guaranteed to fire a `PointerReleased` event; other events may fire instead. For more info, see Remarks. (Inherited from UIElement)
PointerWheelChanged	Occurs when the delta value of a pointer wheel changes. (Inherited from UIElement)
PreviewKeyDown	Occurs when a keyboard key is pressed while the UIElement has focus. (Inherited from UIElement)
PreviewKeyUp	Occurs when a keyboard key is released while the UIElement has focus. (Inherited from UIElement)
ProcessKeyboardAccelerators	Occurs when a keyboard shortcut (or accelerator) is pressed. (Inherited from UIElement)
RightTapped	Occurs when a right-tap input stimulus happens while the pointer is over the element. (Inherited from UIElement)
SizeChanged	Occurs when either the ActualHeight or the ActualWidth property changes value on a FrameworkElement. (Inherited from FrameworkElement)
Tapped	Occurs when an otherwise unhandled Tap interaction occurs over the hit test area of this element. (Inherited from UIElement)
Unloaded	Occurs when this object is no longer connected to the main object tree. (Inherited from FrameworkElement)
