 ## Get the Grouped CollectionView Items
 
 To manipulate the collapsible CollectionView groups, first you will need to call its `GetDataView()` method. In short, the `GetDataView()` method provides a view of the `ItemsSource` after all the sorting, grouping, and filtering operations are applied.

 The CollectionView provides the option to set its [group headers as sticky]({%slug collectionview-sticky-group-header%}). This means the `GroupHeader` UI element "freezes" while scrolling through the items until the whole group is scrolled away. As you scroll through the next group, the currently stuck group header will be pushed by the next group header.
 In a multi-level grouping scenario, the last inner group from the parent group will be sticky.
