The index of the current page if the source is an IPagedCollectionView; otherwise, 0. The default is -1.

Exceptions

Exception Condition
ArgumentOutOfRangeException

Source is nulla null reference (Nothing in Visual Basic) or PageSize is 0, and PageIndex is not -1.

-or-

Source is not nulla null reference (Nothing in Visual Basic) or PageSize is not 0, and PageIndex is less than 0.

Remarks

Dependency property identifier field: PageIndexProperty

If Source is nulla null reference (Nothing in Visual Basic), or if PageSize is 0, PageIndex must be -1. Otherwise, PageIndex must be greater than or equal to 0.

The source typically implements the IPagedCollectionView interface. In this case, PageIndex gets or sets the current IPagedCollectionView.PageIndex of the IPagedCollectionView.

If the source is a collection that implements IEnumerable<T> but not IPagedCollectionView, PageIndex returns 0.
