Methods

The Hub class has these methods. It also inherits methods from the Object class.

MethodDescription
AddHandler Adds a routed event handler for a specified routed event, adding the handler to the handler collection on the current element. Specify handledEventsToo as true to have the provided handler be invoked even if the event is handled elsewhere. (Inherited from UIElement)
ApplyTemplate Loads the relevant control template so that its parts can be referenced. (Inherited from Control)
Arrange Positions child objects and determines a size for a UIElement. Parent objects that implement custom layout for their child elements should call this method from their layout override implementations to form a recursive layout update. (Inherited from UIElement)
ArrangeOverride Provides the behavior for the Arrange pass of layout. Classes can override this method to define their own Arrange pass behavior. (Inherited from FrameworkElement)
CancelDirectManipulations Cancels ongoing direct manipulation processing (system-defined panning/zooming) on any ScrollViewer parent that contains the current UIElement. (Inherited from UIElement)
CapturePointer Sets pointer capture to a UIElement. Once captured, only the element that has capture will fire pointer-related events. (Inherited from UIElement)
ClearValue Clears the local value of a dependency property. (Inherited from DependencyObject)
CompleteViewChange Changes related aspects of presentation when the overall view for a SemanticZoom changes.
CompleteViewChangeFrom Completes item-wise operations that are related to a view change when the Hub instance is the source view and the new view is a potentially different implementing view.
CompleteViewChangeTo Completes item-wise operations that are related to a view change when the Hub instance is the destination view and the source view is a potentially different implementing view.
FindName Retrieves an object that has the specified identifier name. (Inherited from FrameworkElement)
FindSubElementsForTouchTargeting Enables a UIElement subclass to expose child elements that assist with resolving touch targeting. (Inherited from UIElement)
Focus Attempts to set the focus on the control. (Inherited from Control)
GetAnimationBaseValue Returns any base value established for a dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject)
GetBindingExpression Returns the BindingExpression that represents the binding on the specified property. (Inherited from FrameworkElement)
GetTemplateChild Retrieves the named element in the instantiated ControlTemplate visual tree. (Inherited from Control)
GetValue Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject)
GoToElementStateCore When implemented in a derived class, enables per-state construction of a visual tree for a control template in code, rather than by loading XAML for all states at control startup. (Inherited from FrameworkElement)
InitializeViewChange Initializes the changes to related aspects of presentation (such as scrolling UI or state) when the overall view for a SemanticZoom is about to change.
InvalidateArrange Invalidates the arrange state (layout) for a UIElement. After the invalidation, the UIElement will have its layout updated, which will occur asynchronously. (Inherited from UIElement)
InvalidateMeasure Invalidates the measurement state (layout) for a UIElement. (Inherited from UIElement)
MakeVisible Forces content in the view to scroll until the item that's specified by SemanticZoomLocation is visible. Also focuses the item if it finds the item.
Measure Updates the DesiredSize of a UIElement. Typically, objects that implement custom layout for their layout children call this method from their own MeasureOverride implementations to form a recursive layout update. (Inherited from UIElement)
MeasureOverride Provides the behavior for the Measure pass of the layout cycle. Classes can override this method to define their own Measure pass behavior. (Inherited from FrameworkElement)
OnApplyTemplate Invoked whenever application code or internal processes (such as a rebuilding layout pass) call ApplyTemplate. In simplest terms, this means the method is called just before a UI element displays in your app. Override this method to influence the default post-template logic of a class. (Inherited from FrameworkElement)
OnCreateAutomationPeer When implemented in a derived class, returns class-specific AutomationPeer implementations for the Microsoft UI Automation infrastructure. (Inherited from UIElement)
OnDisconnectVisualChildren Override this method to implement how layout and logic should behave when items are removed from a class-specific content or children property. (Inherited from UIElement)
OnDoubleTapped Called before the DoubleTapped event occurs. (Inherited from Control)
OnDragEnter Called before the DragEnter event occurs. (Inherited from Control)

Remarks

Use a Hub to show different collections of data, either from the same source or from different sources.

Hub content

Add content to the Hub by adding HubSection objects to the Sections collection. These sections use a DataTemplate to define the content for the section, and a Header property, which can be any content. If the Header object is a complex data type as opposed to just a string, you can define the look of the header using the HeaderTemplate property.

The Hub uses virtualization to load sections as the user pans. You can handle the SectionsInViewChanged event to respond to changes.

Interactive section headers

You can set the HubSectionHeader.IsHeaderInteractive property is true to let a user navigate to the corresponding app section page. When its IsHeaderInteractive property is true, the default header includes the text, See more. When a user taps the See more text, the SectionHeaderClick event is raised. If you use a custom HeaderTemplate, you should provide similar visual cues to indicate that the header is interactive.

You can handle the SectionHeaderClick event to respond to a tapped header. You get the section that was clicked from the SectionHeaderClickEventArgs.Section property of the event data.

Hub and SemanticZoom

If you declare a Hub as the ZoomedInView of a SemanticZoom, the section headers change to HyperlinkButtons that invoke the ZoomedOutView of the SemanticZoom when they're clicked.

Control style and template

You can modify the default Style and ControlTemplate to give the control a unique appearance. For information about modifying a control's style and template, see Styling controls. The default style, template, and resources that define the look of the control are included in the generic.xaml file. For design purposes, generic.xaml is available in the \(Program Files)\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\UAP\<SDK version>\Generic folder from a Windows Software Development Kit (SDK) installation. Styles and resources from different versions of the SDK might have different values.

Starting in Windows 10, version 1607 (Windows SDK version 10.0.14393.0), generic.xaml includes resources that you can use to modify the colors of a control in different visual states without modifying the control template. In apps that target this SDK or later, modifying these resources is preferred to setting properties such as Background and Foreground. For more info, see the Light-weight styling section of the Styling controls article.

This table shows the resources used by the Hub control.
