'宣言
 
Public ReadOnly Property Items As GalleryItemCollection
public GalleryItemCollection Items {get;}
解説

ひとつ以上の GalleryItemGroup が Groups コレクションに追加されている場合、このコレクションに GalleryItem を追加しても GalleryTool ドロップダウンに GalleryItem は自動的に表示されません。ここで追加された GalleryItem を表示するために GalleryItemGroup の少なくともひとつの GalleryItemGroup.ItemKeys コレクションに少なくともひとつの GalleryItem のキーを追加する必要があります。

注: ここで追加された GalleryItem は、 GalleryItemGroup が Groups コレクションに追加されたかどうかに関係なく GalleryTool プレビュー領域に常に表示されます。
