Remarks
XAML attached properties
PickerFlyoutBase is the host service class for a XAML attached property.
In order to support XAML processor access to the attached properties, and also to expose equivalent get and set operations to code, each XAML attached property has a pair of Get and Set accessor methods. Another way to get or set the value in code is to use the dependency property system, calling either GetValue or SetValue and passing the identifier field as the dependency property identifier.
| Attached property | Description |
|---|---|
| Title | Gets or sets the title for a picker flyout when it appears.
|
Constructors
| PickerFlyoutBase() |
Provides base-class initialization behavior for classes that are derived from the PickerFlyoutBase class. |
Properties
| AllowFocusOnInteraction |
Gets or sets a value that indicates whether the element automatically gets focus when the user interacts with it. (Inherited from FlyoutBase) |
| AllowFocusWhenDisabled |
Gets or sets a value that specifies whether the control can receive focus when it's disabled. (Inherited from FlyoutBase) |
| AreOpenCloseAnimationsEnabled |
Gets or sets a value that indicates whether animations are played when the flyout is opened or closed. (Inherited from FlyoutBase) |
| Dispatcher |
Always returns |
| DispatcherQueue |
Gets the |
| ElementSoundMode |
Gets or sets a value that specifies the control's preference for whether it plays sounds. (Inherited from FlyoutBase) |
| InputDevicePrefersPrimaryCommands |
Gets a value that indicates whether the input device used to open the flyout does not easily open the secondary commands. (Inherited from FlyoutBase) |
| IsConstrainedToRootBounds |
Gets a value that indicates whether the flyout is shown within the bounds of the XAML root. This property is always true for Windows App SDK apps. (Inherited from FlyoutBase) |
| IsOpen |
Gets a value that indicates whether the flyout is open. (Inherited from FlyoutBase) |
| LightDismissOverlayMode |
Gets or sets a value that specifies whether the area outside of a light-dismiss UI is darkened. (Inherited from FlyoutBase) |
| OverlayInputPassThroughElement |
Gets or sets an element that should receive pointer input events even when underneath the flyout's overlay. (Inherited from FlyoutBase) |
| Placement |
Gets or sets the default placement to be used for the flyout, in relation to its placement target. (Inherited from FlyoutBase) |
| ShouldConstrainToRootBounds |
Gets or sets a value that indicates whether the flyout should be shown within the bounds of the XAML root. (Inherited from FlyoutBase) |
| ShowMode |
Gets or sets a value that indicates how a flyout behaves when shown. (Inherited from FlyoutBase) |
| SystemBackdrop |
Gets or sets the system backdrop to apply to this flyout. The backdrop is rendered behind the flyout content. (Inherited from FlyoutBase) |
| Target |
Gets the element to use as the flyout's placement target. (Inherited from FlyoutBase) |
| TitleProperty |
Gets the identifier for the attached title property. |
| XamlRoot |
Gets or sets the XamlRoot in which this flyout is being viewed. (Inherited from FlyoutBase) |
Attached Properties
| Title |
Gets or sets the title for a picker flyout when it appears. |
Methods
| ClearValue(DependencyProperty) |
Clears the local value of a dependency property. (Inherited from DependencyObject) |
| CreatePresenter() |
When overridden in a derived class, initializes a control to show the flyout content as appropriate for the derived control. Note: This method has no base class implementation and must be overridden in a derived class. (Inherited from FlyoutBase) |
| GetAnimationBaseValue(DependencyProperty) |
Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject) |
| GetTitle(DependencyObject) |
Gets the title displayed on the picker control. |
| GetValue(DependencyProperty) |
Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject) |
| Hide() |
Closes the flyout. (Inherited from FlyoutBase) |
| OnConfirmed() |
Notifies PickerFlyoutBase subclasses when a user has confirmed a selection. |
| OnProcessKeyboardAccelerators(ProcessKeyboardAcceleratorEventArgs) |
Called just before a keyboard shortcut (accelerator) is processed in your app. Invoked whenever application code or internal processes call ProcessKeyboardAccelerators. Override this method to influence the default accelerator handling. (Inherited from FlyoutBase) |
| ReadLocalValue(DependencyProperty) |
Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject) |
| RegisterPropertyChangedCallback(DependencyProperty, DependencyPropertyChangedCallback) |
Registers a notification function for listening to changes to a specific DependencyProperty on this DependencyObject instance. (Inherited from DependencyObject) |
| SetTitle(DependencyObject, String) |
Sets the title displayed on a picker control. |
| SetValue(DependencyProperty, Object) |
Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject) |
| ShouldShowConfirmationButtons() |
Gets or sets whether confirmation buttons should be shown in the picker. Note: This method has no base class implementation and must be overridden in a derived class. |
| ShowAt(DependencyObject, FlyoutShowOptions) |
Shows the flyout placed in relation to the specified element using the specified options. (Inherited from FlyoutBase) |
| ShowAt(FrameworkElement) |
Shows the flyout placed in relation to the specified element. (Inherited from FlyoutBase) |
| TryInvokeKeyboardAccelerator(ProcessKeyboardAcceleratorEventArgs) |
Attempts to invoke a keyboard shortcut (accelerator). (Inherited from FlyoutBase) |
| UnregisterPropertyChangedCallback(DependencyProperty, Int64) |
Cancels a change notification that was previously registered by calling RegisterPropertyChangedCallback. (Inherited from DependencyObject) |
Events
| Closed |
Occurs when the flyout is hidden. (Inherited from FlyoutBase) |
| Closing |
Occurs when the flyout starts to be hidden. (Inherited from FlyoutBase) |
| Opened |
Occurs when the flyout is shown. (Inherited from FlyoutBase) |
| Opening |
Occurs before the flyout is shown. (Inherited from FlyoutBase) |
