When the control is in the expanded state, groups and items are displayed at their normal size. Items respond to user interaction, and can be activated or selected.
When the control is in the collapsed state, groups and items are displayed at a smaller size. Groups respond to user interaction, and can be activated or selected. When in this state, items are not UI active.
Tiles display their CollapsedImage when the Expanded property is set to false. If no collapsed image is defined, the tile's logo is displayed (for live tiles), or its image (for static tiles).
The control can be expanded/collapsed via a button which appears at the bottom right corner of the control. This button's visibility can be controlled via the ExpandButtonVisibility and CollapseButtonVisibility properties. On gesture-enabled devices, the expanded state can be changed via "zoom" and "pinch" gestures.
Note that changing the value of this property causes the SelectedTiles collection to be cleared.
