IsOpen プロパティは、それが折り畳まれているか QuickAccessToolbar 内に表示される時、RibbonGroup を開くまたは閉じるために使用されます。RibbonGroup が開かれると、コンテンツ（その System.Windows.Controls.ItemsControl.Items および Caption と Caption を含むキャプション領域）を表示するポップアップが表示されます。値を変更すると Closed イベントまたは Opening%E:Infragistics.Windows.Ribbon.RibbonGroup.Opened% イベントが起動されます。
注: IsOpen プロパティは、IsCollapsed が True またはグループが QuickAccessToolbar 内に表示される場合、RibbonGroup に限って使用されます。
