The index of the item.

A UIElement that corresponds to the item at the specified index. If the item is not realized, a new UIElement is created.
Remarks
This method does two things:
- Gets a UIElement that corresponds to the item in the data source at the specified index. If necessary, this method causes a virtualized item to be realized and creates a new UIElement for it.
- Queues that element on the next layout pass as the suggested anchor for the layout to use as a starting point.
