Remarks
VirtualizingStackPanel can only be used to display items in an ItemsControl. A primary scenario for VirtualizingStackPanel is that it provides the items panel template behavior for FlipView and ListBox in default templates.
Note
Starting in Windows 8.1, ItemsStackPanel is used as the default ItemsPanel for ListView. If you modify the ItemsPanel, we recommend you use ItemsStackPanel or ItemsWrapGrid instead of VirtualizingStackPanel or WrapGrid.
XAML attached properties
VirtualizingStackPanel is the host service class for several XAML attached properties.
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.

| VirtualizationMode | Gets or sets a value that indicates the virtualization mode of items being virtualized by a parent VirtualizingStackPanel and items set. |

Occurs when the input system reports an underlying drop event with this element as the drop target. (Inherited from UIElement) |
| DropCompleted |
Occurs when a drag-and-drop operation with this element as the source is ended. (Inherited from UIElement) |
| EffectiveViewportChanged |
Occurs when the FrameworkElement's effective viewport changes. (Inherited from FrameworkElement) |
| GettingFocus |
Occurs before a UIElement receives focus. This event is raised synchronously to ensure focus isn't moved while the event is bubbling. (Inherited from UIElement) |
| GotFocus |
Occurs when a UIElement receives focus. This event is raised asynchronously, so focus can move again before bubbling is complete. (Inherited from UIElement) |
| Holding |
Occurs when an otherwise unhandled Hold interaction occurs over the hit test area of this element. (Inherited from UIElement) |
| HorizontalSnapPointsChanged |
Fires when the measurements for horizontal snap points change. (Inherited from OrientedVirtualizingPanel) |
| 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) |
| 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) |
| VerticalSnapPointsChanged |
Fires when the measurements for vertical snap points change. (Inherited from OrientedVirtualizingPanel) |
