IVirtualizedItemProvider Interface

  • Article

Exposes methods and properties to support the virtualized item control pattern.

IVirtualizedItemProvider Members

Realize Makes the virtual item fully accessible as a UI Automation element.

Remarks

A virtualized item is typically an item in a virtual list; that is, a list that does not manage its own data. When an application retrieves an IUIAutomationElement for a virtualized item by using IUIAutomationItemContainerPattern::FindItemByProperty, Microsoft UI Automation calls the provider's implementation of IItemContainerProvider::FindItemByProperty, where the provider may return a placeholder element that also implements IVirtualizedItemProvider. On a call to IUIAutomationVirtualizedItemPattern::Realize, the provider's implementation of IVirtualizedItemProvider::Realize returns a full UI Automation element reference and may also scroll the item into view.
