You can format bar item text (BarItem.Caption and BarItem.Description) using HTML tags. To enable this feature for all bar items, set the BarManager.AllowHtmlText property to true. Or, you can enable this feature for individual bar items by setting the BarItem.AllowHtmlText property to True.
If HTML formatting is enabled for all bar items via the BarManager.AllowHtmlText property, you can still disable this feature for individual items by setting the BarItem.AllowHtmlText property to False.
