Edit

Exposes methods and properties to support access by a Microsoft UI Automation client to a control that acts as a scrollable container for a collection of child objects. The children of this element must implement IScrollItemProvider. Implement IScrollProvider in order to support the capabilities that an automation client requests with a GetPattern call and PatternInterface.Scroll.

Remarks

This pattern has guidelines and conventions that aren't fully documented here. For more info on what this pattern is for, see Scroll Control Pattern.

IScrollProvider is implemented by the existing Windows Runtime class ScrollViewerAutomationPeer, which is the peer for the ScrollViewer component part used in many other list controls.

Also, IScrollProvider is reported as a supported pattern by ItemsControlAutomationPeer, but only if a ScrollViewer exists in the owner's template and is active. The ScrollViewerAutomationPeer for this ScrollViewer provides the pattern implementation, ItemsControlAutomationPeer is only forwarding it.

Use ScrollPatternIdentifiers if you want to reference the IScrollProvider pattern properties from control code when you fire automation events or call RaisePropertyChangedEvent.

Properties

HorizontallyScrollable	Gets a value that indicates whether the control can scroll horizontally.
HorizontalScrollPercent	Gets the current horizontal scroll position.
HorizontalViewSize	Gets the current horizontal view size.

VerticalScrollPercent	Gets the current vertical scroll position.
VerticalViewSize	Gets the vertical view size.

Methods
