Where a title region is positioned on a surface is determined by each multi-surface theme, which can also support more than one position for some surface configurations (see Table 1). As such, each multi-surface theme that supports multiple title-region positions exposes a TitleRegionPosition attached property that is specific to the theme and which can be set on any of the surface configurations it supports. The TitleRegionPosition property can also be set directly on the theme to change the title-region position of all the applicable surface configurations.
Table 1: Supported title-region positions
| Theme | Surface configuration | Positions | Enumeration |
|---|---|---|---|
| Elemental Blue, Black, and Silver themes | TitleSurfaceConfiguration | Top, Middle, and Bottom | ElementalTitleRegionPosition |
| Elemental Blue, Black, and Silver themes | ImageAndTitleSurfaceConfiguration | Top, Middle, and Bottom | ElementalTitleRegionPosition |
| Chameleon theme | TitleSurfaceConfiguration | Left and Right | ChameleonTitleRegionPosition |
| Chameleon theme | ImageAndTitleSurfaceConfiguration | Left and Right | ChameleonTitleRegionPosition |
| Chameleon theme | CompleteSurfaceConfiguration | Left and Right | ChameleonTitleRegionPosition |
| Chameleon theme | TitleAndDataSurfaceConfiguration | Left and Right | ChameleonTitleRegionPosition |
